This is pure class.
The man that wrote the book was man enough to be humble when he owned up to missing something.
I’m a maintenance electrician with 40yrs experience and I’ve been learning from Paul’s videos for a long time. $11 dollars a month for Scanner Danner Premium is amazing value for money.
I don’t change parts in the hope of fixing something; I apply what I learn from Paul’s instructional videos to electrical and electronic machinery (not just cars) and I am glad to say I’m not known as a parts changer.
Scanner Danner Premium is my online classroom and Paul is a fantastic teacher.
Thanks Paul.
How does this information cross over into non-automotive applications?
.i agree
I have never wanted to be called a parts swapper. I have worked at shops where the guys learned to tell more believable lies than if they had actually tried to learn how to troubleshoot the actual failure.
You are the man. I was a factory trained Ford tech until 1988. I haven't worked on many cars since then but I was certified by Ford as an EEC IV Specialist. I will say that I have forgotten more about cars than most common people will ever know.
I find a lot of people here on You Tube trying to help by supplying us with helpful information and I must say that you are one of the best I've seen. The one most favorite characteristics about you is that you don't like to guess and you tend to question your own diagnosis until it has been proven to be the problem.
I was intrigued by this video because back around 1985 or 86 I had an Escort with this type of problem. I've never seen it before so I thought I was going to see it again. Your issue was different than mine as the Escort in question had TFI I not TFI IV. This means it was a 3 wire module without a spout wire.
It was brought to our dealership from another shop who claimed to have changed everything and although it would start, under heavy acceleration, it would loose spark. in the end, after about 5 days of part swapping, I hot wired it bypassing all of the on-board wiring. When that fixed it, I swapped the entire engine wiring harness from a new car on the lot. That didn't work. So I hot wired it again and it ran fine.
As it turned out, applying voltage to the "start" circuit of the module would cause this problem. When I hot wired it I only applied voltage to the "run" circuit. I call a DSE (District Service Engineer) and explained my findings and we agreed to cut the "start" circuit wire about 3 inches from the module plug, tape it up, walk away and don't look back.
It was a successful repair but I never made sense from it. Keep up the good work. We all appreciate the efforts you put into your videos.
+ELtee555 thanks so much! crazy stuff man
I have a lot of respect for you Paul...thanks to YOU not only am I ASE L1 certified, but I made a perfect score on 3 out of 5 sections of that test......could not have done it without you.........takes a real man to get online and admit he made a mistake...cars do get the best of us sometimes....I feel your pain.
Thanks so much Jerrod! Made my morning
I found your channel on a link from Eric the Car Guy, and I'm so glad I did. I have been driving these old Fords my whole life, and partly from yours and ETCG's videos, I've learned how to do actual diagnostic work instead of just changing parts 'til it runs. Thanks a lot, and keep up the good work!!!
scanner danner you are the man !!!! you are the one that propelled me to be the mechanic i am today. i appreciate the time and effort you put on these amazing videos. I just work on a 87 ford f150 4.9 last week. same problem no spar. but it ended up being a bad module that came with the NEW distributor. That truck kicked my butt as well, but luckly I ended finding the problem. big props... keep up the good work. I been inspired by your videos, actually been making some myself. thanks from texas
I don't care what your hater says Ha. That is real shop stuff. Most of us dealing with that old technology would be just as confident with the module call. What u show is that no one is a God here with diagnostics. No matter how long u been doing it. Even to the point of being able to teach it. What separates you from a lot is 1) having the balls to post it 2) not being satisfied until you and we understand what went on here 3) and not caring that Pete didn't get to eat dinner with his family.ha
Lol nice. Thanks brother. Didn't think you had time to watch my videos. Guess it was the title that sucked you in huh? Wanted to see your little bro get schooled by an old truck?
Thanks Danner!
I got beat up by a f250 big block 7.4l . Same spark system. Mine originally would only stall on a Friday at 5 o'clock in finleyville. Then get towed in. My original issue was no pip. Did the module too cause it was cheap. Week later its back. I got some real weird readings but no pip again. Got another distributor and it fired right up. But my initial weird readings the second time coupled with this new video have me a little concerned of another failure. Google searching does show harness concerns at least on the v8s. I could talk all day on this. Great video brother
I hope for your sake it was the distributor.
You going to do a video if it comes back?. I'll stop by the shop and we'll promote it.
Ford is notorious for electrical and ignition design problems. My headlights suddenly went out on a mountain highway, and found out later that ford runs all the power through the headlight switch without using a relay. But hopefully our Aerostar was just a ford fluke!
James Danner i am what you call a long time DIY-er. that's right i do my own repairs and i have done almost everything. i have a 1996 camaro Z28 with the LT1 and that car stumped me hard. i replaced the opti-spark with a delphi, yes the original was BAD. i ended up being a bad ground but it took forever to find. im pretty happy with the way the car runs, which is excellent that car is damn quick for stock. anyways i learned allot about the opti-spark ignition system on the project. i still have the car and drive it regularly
I would have NEVER called that spout. I just would have never thought to look there, dang did I learn a lot in this video. As the saying goes you learn something new every day. And if you are not, then you are hanging out with the wrong people. Thanks for the post. These types of videos are the most informative.
Great vid Paul! I'm relieved to know that even the very best in our field mis something every once in a while. The way you speak about your next diag step and thoughts out loud is really what makes your vid so great. Thank you.
I'm am certainly not the very best, not even close but I appreciate your comments. Thank you!
Just kidding , I've learned a lot from your videos. My ranger was killing me. I'm not a mechanic, or electrician. Bought cheap multimeter and test light. No money no wiring diagrams. Everything checked out . replaced . crankshaft & cam position sensor. Still no start. Finally notice exiter plate had spun on hormonic balancer. Would have never got that far without you and others videos. I thank you kind sir. Oh 3 weeks I worked on it and was ready to commit Harry Carey,
People don't realize how hard it is to work on vehicles
All the respect to you Dan! Thanks for this video on an older F150. A buddy has the same truck with 351, so the info may be helpful to us up here in Canada. (Not many around but a couple you see from time to time) You fixed it, move on to the next job! 😊
Thanks once again Paul, for everything you do on this community, and that's one of the reasons why I want to go To Rosedale Technical Institute and be in your class, because your are so down to earth and unlike others you are real and honest enough to admit when you make a mistake. Am taking as many notes as I can on my paper book to be ready by the time is time to be in your class.
Great video Paul. A learned lesson is a remembered lesson. That applies to more than just auto repair.
Thanks for posting !!!
I really liked it Paul. Your never surrender attitude is a great lesson for your students as well as all of us that enjoy your videos. Thanks!
Great video! I have a 1988 Bronco II that I bought new in 1987. It's not my daily driver; I mostly use it when I'm planning on going down dirt or 4WD roads. I do almost all the work on it myself so it's very helpful that you cover this system in your videos. Thanks for putting this video out there.
Excellence as allways! I've faced that problem before and failed. Anyone that can't understand what happened there hasn't worked on enough TFI's. The 90's were hard on techs and problems like that can destroy a guy's reputation as a good diagnostition.
This are the vids that show that you can't ever get to relax at diagnostics you never know 100% there is always that chance thanks for sharing
Intermittent problems with wiring issues and grounds sometimes throws a curve ball. And great techs. And instructors with yrs of hands on experience are priceless.Great job Master Tech./Teacher.
Don't feel bad Paul, can't win them all. Sometimes it seems to me we learn the best and remember the best when we get our buts kicked. Been there and done that. Thanks for sharing.
I want to take a moment and thank you scannerdanner. I bought a vantage mt2400 off of ebay, and the reason I bought it was because of the way the seller explained how it just shut off and wouldn't come back on and he said he could hear something rattling around inside of it. I knew at that very moment the battery terminal had came unsoldered. so I bought it and sure enough that's exactly what it was. I fixed it and its been one of the best lil diagnostic tools I own. they are going for around $500 each and i only have $30 invested in mine, so thank you so much. You are one hell of a diagnostic mechanic.
Thanks again Sam☺
That's freaking awesome
Thank so much for these videos on this f150 . I just went through the exact same thing with a 96 f250. Up and running . It had a weak coil and a bad ignition module . Did all the research. Performed the voltage tests as you teach and proved the the parts were bad . Ps after changing the ignition module I had weak spark at the coil. Thank you for your trouble mr. Danner . Bill Grimsby Ontario Canada
I do not currently have this problem, but I do really appreciate all the info here. I have a 1990 with the same setup here. Its nice to have all the info for future problems. My truck is 33 years old, and i plan on having it for at least 20 more. Ive recently changed dam near everything under the hood, trany and transfer case. Im about 20 grand into it to date and feel its all been worth it. I love this truck and with the info here, maybe I can keep it going for a little bit longer. Thanks so much for taking the time to share your knowledge. You said you dont think there are to many of these things still on the road. Still seeing quite a few here in the great northwest..... Thanks again
I picked up a 78 Powerwagon and I'm surprised at the amount of old dodge trucks still on the road!
This video is just exactly what I needed to watch thank you very much and thank you for being so thorough on each circuit
Hey Scanner Dan, I'm having the same issue with my 1988 E250 4.9l. , I replaced the ECM when I first bought it, as it would run on propane, not gasoline. Well that worked for 30,000 miles. And one day it sputtered and died. I checked the inertia switch it was connecting. Checked the PIP, that was good. Down the road I replaced the high-pressure pump, replaced both relays. ECM, and fuel pumpI figured we were back to the ECM again. Bought another A1 Cardone unit. Still no go. I can hear the pumps running, but it does not dead heading as it should, just keeps on running on.
I forgot mention the pumps run only when I jump the two terminals of the fuel pump relay socket #3 and #4 the red and yellow wires. Not get a signal to run when switch is turned on. I do have a constant spark from the coil. I am beside myself on this. I've been a mechanic for 50 years, mostly on heavy equipment.
Learning all about this new electronic fuel injected gasoline engines' hit. I am to the point of about putting a carburetor back on this 300 six. What can you suggest? Can you teach this old dog, some new tricks! Thanx, Brian
Great job, great video. I like your honesty, this reflects live work. Thanks Paul.
Paul, this is a very nice video. I appreciate the honesty and its nice to see that I am not the only one to make mistakes. Keep up the wonderful work!
Love your videos I allways get something out of it. Thank you for sharing your humbling experiences as well .
Nice video bro, love to see these older vehicles like this because it's so hard to find anything on them... Good job man, helped me a lot with my 89 4.9!
The most amazing thing about this video is a 1988 vehicle with a working E-brake. Good video Danner!
Or did it :)
I know video is way over 2 years old. But the foxbody mustang from 86 to 93 all use the TFI eec-iv and this is great troubleshooting for that ignition system. Thanks for the video.
I have a 91 version of this truck, same engine. The truck would randomly die. Then I could restart it five minutes later. After a few days it was completely dead. The fuel pump would not come on. There's no proper wiring diagram for this truck on the planet but I was lucky to find the fuseable link. The EEC relay was pretty corroded so I imagined it probably drew too much current tripping the link. It also killed my fuel switch. I replaced the connector and relay and ran a new fuse (maybe I shouldn't have done that). Now it works. I learned so much about diagnosing problems from that experience. I also learned a lot more from this video.
I liked it`s refreshed memories went I used too work FORD cars Dealer ... we build a tool that bypasses the module & spout..so we don`t have too push this cars and truck back to the garage on bad weather ...the tool is just a good module and cut a piece of metal of the same diameter of the module so do not overheat and go to a junk yard and get cut the harness side connector..i will send u a picture of the one I have... continue with the good work you are doing ... you have my respect and I been in this business more than 40 years ...
Pete Sambolin can you post this "module" that you built? Thanks
I was on the edge of my seat during some of that cranking as after reading the title I thought the coil bit you. Well done though!
Thanks for making this video helped out so much. I still have a no spark on my 88 ford e-350 with a 460ci. Installed a new pick up coil well before I came across your video. I'm at the conclusion that there is no trigger. My problem is that once you rolled out the pick up coil, you where done with that part(its evident that it works, the hall effect worked when you bumped the engine while you were checking the pip). I need to know how to rule out the pick up coil with just my dom and my probe. Really just think I need the pin outside and ohm it while I run some metal through the magnet. Help scanner Dan. Thanks Chris
Thanks, Dan. I wallowed around with this for awhile and found a bad EEC relay,
Thanks Todd and nice job!
My name is Paul Danner btw 😉
Paul, watching your videos makes me realize that if you want to be a great technician you can't be a parts changer. Your methods are jus sensational, I've learned so much from you, starting with how to use a test light to check for power on different areas, the 5volt check etc. Car mechanics have changed a lot and you're giving us the tools to adapt to the new era of automotive diagnosis processes. The "mistake" you made here is just true wisdom for us who follow you, and teaches us to always go through the basics. No need to feel bad for this. I really appreciate all your work Paul. All I can say is thank you.
+Moving Up DIY thanks man! great user name too! you really are
+ScannerDanner thanks. Shalom.
+Moving Up DIY peace to you too my friend! Love that word "Shalom"
+ScannerDanner yeah me too. That's how Yeshua (Jesus) tauhgth us to greet ;)
+Moving Up DIY awesome! thanks for sharing.
But doesn't that word date even before Jesus came?
I was thinking old testament times?
Scanner danner you will always be my favorite teacher man I truly appreciate you
Dude I got so psyched for this video when I saw the title!! Coincidence: just spent three days getting my butt kicked by a '89 Bronco II 2.9 V6 with a misfire at my friend's garage. I'll try to post the details in a separate comment if RUclips cooperates :)
I see this one.
ScannerDanner Premium
OK I re-posted the longer one on RUclips; if you still can't see it might try doing it through Google Plus...
Excellent work! Love learning from your channel sir
Reminds me of the no-start hell I had with my Escort wagon a few months back. Turned out to be a broken wire in the harness. I bypassed it like you did temporarily then cut the harness open and rewired it (with trailer wire of all things) once I knew I was in good shape.
man ill be honest i woulda had no fn clue how to fix this and i woulda told whoever sorry bro take it to a shop cuz i cant figure this out... scanner you are a TRUE PRO.. hats off to u homie
Its a win to me. It actually helped me figure out something on my car and now my truck as well. Its all good to know. ScannerDanner just made my day again. :)
I have an 88 Bronco. This video was invaluable to me. You’re the man!!
Lol. Fricken flashbacks. Tgif modules. Great seeing a new video. Love that old vantage.
Grate video!
Only people who did not work at a car, could not apreciate your efforts.
My truck wont start its an 87 f150 and I've replaced everything I can afford fuel pump sparks distributor belsts checked timing nothing seems to work but I don't want to pay a mechanic to tell me something I already know!. I'm glad you got this one back to health!
Great video. Sometimes your the bug, sometimes your the windshield lol. You got it going and that's what counts.
Haha great analogy
That was brilliant mechanics from a pro u saved the ford at the end of the day what counts is that the damn thing woke up big up danner.
I don't think that this was a screw up or a butt kicking. This is automotive work. Sometimes you zero in on a solution but can be blindsided by a minor detail that you might of overlooked. This video shows that you are a true professional and that you backed up and covered all your base's when your original diagnosis was off, found the actual problem and fixed it. Good job.
Great video !!! I learn so much when I have to work for the solution. Awesome you tube channel. I'm hooked mister !!!
Thanks man great info and that is exactly what was wrong with my 87 4.9 corroded wire at the connector.
Hi Paul,great video! There are a good number of these old EEC-IV vehicles out here in the west, still running! I'm fighting a ford with is exact problem! Thanks!
Man you just know to much! You simply outpaced yourself. You got thrown a curve ball but recognized it immediately and regrouped.. Thanks for keeping it real! I know you keep the best content for scannerdanner "international":) premium channel. Can you make some of the field work as part if not all scannerdanner regular channel? For some of us peons like myself..
Thank man. And I wouldn't say I keep the best for my paid channel, just different. I want to keep this channel filled with great content too!
ScannerDanner Premium lol man thought you had gone all the way Hollywood on us. Post got few far & between. But I understand when you are trying to build something and maintain it.. + other obligations. Its all good man.
Man this brings back memories of my first truck, an 89 F-150 with the 300 inline 6. Died once, needed a module. Died another time, blown fuseable link. Died once, bad alternator. Died once, seized air pump threw the belt. Died once, fuel pump. Learned so much about wrenching trying to keep that thing running. I think I still have the old blue Haynes manual that I bought at Autozone. Can you even buy those anymore?
This is similar that i found low voltage feed to the alternator not charging. just .5 volts drop was all it was. That was a feed through a fused link at the battery. It was a corroded splice of 4 wires. I bypassed the splice and it works good now. Ford splices are welded with no crimp band, not the best but the cheapest for production.
Great video!
Where was this video back when I was in high school driving my '84 Bronco 2 that had the EEC-IV system with the computer controlled carburetor? (I'm about the same age as you). Seriously, this was awesome. It was black magic back then, but seems so simple now, thank you. I'm contemplating putting a 89-ish 5.0 in my classic Mustang, and this applies to that as well. Oh, and the family 94 Ranger with EEC-IV is still chugging along, although it's DIS with waste spark.
one thing I learned on my 1995 f150 is to always be sure you have a good ground on the test light. I have heard you say it before. I chased wires and grounds that weren't broken for days when I had a bad fuel pump all along. I knew the fuel pump wasn't running but I jumped the test port and didn't get power at the fuel pump plug. turns out I did but my ground on my test light wasn't good and I was mistaken. couple that with a fuel pump that was just running at ok pressure just the day before and my denial that I would have to drop the tank or pull the bed. That little ground check could have saved me hours of frustration.
Would be interesting to find out if the module actually had gone bad.... That's what I would have done! Love these videos, don't know why but, these days, they are about the only thing that manages to get my full concentration for more than 30 mins. Love to see more "old" cars with no obd, you learn so many interesting techniques that don't require expensive tools. If you ever get your hands on an Alfa Milano, please make a video. Would be interesting to see how you get on with an old, temperamental Italian car....
I know you're right on no crazy equipment , just experienced inmechanical is enough,, sensors are more of a pain tha their worth!
I wish I could find a shop in my area that put as much effort into their work as you do
Goddamned TFI modules. It's always the TFI module.
Love to see videos on EEC-IV.
brakedd There was a class action lawsuit against Ford about the module.
brakedd This was a good reliable Ford system had many. No issues in trucks a few modules and starters etc.
I just had a 1988 bronco 5.0 kick my you know what, it was a no start, we had spark and fuel pressure, but noid light was faint to non existent. Went through all power and Grounds, tracing wires for insulation being deteriorated, rubbed through etc... Replace ECM, No Fix! Truck never even acted like it wanted to start, Eventually by chance unplugged MAP Sensor, Truck started, Unbelieveable. Replaced Map sensor, Sent Customer down the road, Boy What a Lesson.
Sam Tedder
I have a 88 f150 4.9 5spd , fuel pressure is 50 psi ,noide light used and injectors have pulse , has spark , new distributor , plugs , wires etc , truck will run with ether and gas sprayed into throttle body , but will not start with out spraying gas in throttle body . I'm stumped . Any ideas ? Or if anyone see this and has any idea please help me , call me or.text me 5403881364 , I can not figure this truck out . Am I missing something ?
This engine and its operation is in good condition but its the engine itself is a bloody sick puppy to deal with but unfortunately for the block your the cure for its illnessess. And now its showing why its power relay is too low on its voltage, but too afraid to show itself for its final inspection!. Their power relay buddies will be in for a shock treatment, even at the end of their own pulse width lol ha ha ha.....
I got a 4.9 sat 3 years, map can go bad sitting ? Crank no start, fuel pumps prime
Just my scenario, I was going to condemn the computer on 2000 e150 , but this show up
Perfect timing Mr danner
Always learn from the best
Thanks
nice! makes all the pain yesterday worth it.
Thanks for this video. I am sorting a similar problem on a 1990 E350.
let he amongst us who has not eaten an ignition module cast the first pip or coil or whatever the case maybe for it is written or somebody said it "to err is human" and while we may take comfort knowing someone somewhere is casting dispersion on the genius/moron who dremped up the fusable linc. in all honesty Thank you for everything you shown and explained , great videos and channel I've learned so much about OBD ll just wanted to say thanks
I broke down today it took 40 minutes to jump the ecc relay! Great video, I didn't know what exactly the spout conn was.
typical shop owner, very funny at 12:40 "I'm not paying for that" or "i'm not paying for your time", its great to see that you are still down to earth to upload this in its entirety, even though you reference your book quite a bit - and that's fair, we all have to eat...
good learning opportunity, glad you found it and documented.
great video scanner danner,no one is perfect and i think a great lesson was taught here
On my now sadly retired (to the scrap yard with 328 K miles) "86 F 350 I had ECM failures on a pretty regular basis so that I carried a spare in the truck. Failure was typically intermittent and only when hot. A hand full of snow or an iced drink cup placed on the ECM to cool it usually returned functionality. Early on i also had connector issues, so I removed the connectors and soldered the wires to join them. Wire nuts worked when i did a replacement in the field and then solder back at the garage.
Glad you did this vid. I have a 94 probe with no spark and its looking like this may be the problem with it also. Its been a long time for me also with dealing with old technology
Have you managed to fix the problem? I also have a 94 probe, with pretty weak sparks, injector pulse but only running on 3 cylinders... AND no communication with the ECU (no engine light when I jump a wire for diagnosis...). Pretty desperate with this car..
Hey Paul, I own a 1986 Ford Mustang GT 5.0 sequential fuel injection and I have the factory manuals on the vehicle it was interesting to see that when you unplugged the spout connector that the vehicle started. On my diagrams for the start ignition Circuit the starter relay provides a 12 V start signal into the TFI ignition module via pin three of the ignition module, and the literature states that during cranking the ignition module only uses the PIP signal due to the fact that the ignition module knows the car is cranking is it possible that due to the voltage problem at the CPU that that start signal is not getting to the TFI module and therefore it's relying on this SPOUT signal to fire the coil but as we know the SPOUT signal was very weak at four VOLTS.
THANKS PAUL, BEST SUBSCRIPTION FOR DIAGNOSTICS!!!!
Thanks for keep it real. Love your video, most guys wouldn't have post this. This shows guys like me you've gotta think. Thanks
Yep us mechanics...still only human..
Just finished the video, this is one of the best you'vedone. It might have gotten you but you did beat it in the end. It wasn't a failure.
I hate hate hate those fusible links. I cut out every one of them on my EEC-IV car, replaced with a fuse box from a later model and matched the fuses according to the gauge of wire/fusible link. It also cleaned up the rats nest of wiring that lived on the inner fender of most 80s Fords.
Next no-start I get on an EEC-IV I'm pulling the spout. I'll look like a damned wizard if it works.
Got any more "failure" videos?
I've got the same problem w one currently and here I am, appreciate the insight brother in wrenches....shit happens, been in the field long enough to know this.
If I was half as good as you I would still be a great tech , great video Thanks for all the knowledge you a impart on us
Awesome! Honesty is the best policy, good stuff! About to get one of them trucks, now I know..
If Eric the Car guy is the general surgery guy, you are the neurosurgeon guy lolol. Subbed and Liked!!!!4
That being said I think you would have been a good doctor. Your mastery of the scientific method and diagnostic abilities would have helped a lot of people.
Tell my friend Eric I said hello and to keep up the great work. I consider him the godfather of RUclips auto channels.
I remember seeing an ad in a Car magazine showing a mechanic sitting with his hands in his face trying to figure out a car. It showed the Troubleshooting light and it was after hours. He knew that he wasn't getting paid after hours and he's GOT to fix that car. He can't go home until it's fixed. THAT'S what being a mechanic is REALLY like!
Don't be too hard on yourself. No matter how knowledgeable we are we always try the easiest most probable component to condemn first. We still have a customer with the exact same truck so if it ever stops running I certainly will remember your video. After 47 years in the trade I still get bit every so often.
This taught me a valuable lesson, i recently got my ass kicked by a 1996 mazda protege, i ruled out all the hard stuff first and forgot to check the basics.
Thank you ScannerDanner.
I tell ya being in this business more often than not when vehicles get sent to me from other shops or dealers it's just that. Someone thought way to hard and forgot the basics.
Totally, now I learned my lesson.
Happens to the best of us, I hope we are never done learning.
The day we stop learning, we die, just like that.
True story ^

Wire changed color? Not surprised at all. I had a '89 Bronco 4.9L. It had parts from '84, '86, '88-'89.
My '95 Bronco has a similar no start/no spark problem, but I could only get a result from half the tests. Pulled the computer, opened it up and found two burnt capacitors. When the new one goes in I pray to god it starts. Been down the fuse link road....
You are so methodical.
Thanks allot.
I know this is old but good info. Not many guys out there that know what EEC-IV even is. I had one in the shop about a month ago with no spark. Cheap assed aftermarket distributor had actually sheared she roll pin holding the Dist. gear on. Luck was with me, the gear and all the washers dropped onto the ledge and I was able to grab them out with a magnet. The roll pin was paper thin. I replaced it with a heavy one, slammed it back together and shipped it. ;)
LOL at 13:38 UH! "That's not cool" One of my all time favorite sayings. It's Funny how Fords make you say that especially those 80's models. I learned something though so that's what it's all about. thanks danner.
You are forgiven !!!! Great job, keep 'em coming!
When they decided to go to MORE and MORE electronic controls, these crazy problems build up. Things were so much simpler years ago.
But using good diagnostic procedures helps to pin point the offensive part.
Wow, a broken wire to the relay that controls the power to the computer (EEC)? To me, those kind of electrical problems are the hardest to diagnose. Great work!!
Just knowing the fundamentals of the system was the key on recognizing what we had. But thank you!
I wouldn't be so hard on your miss diagnosis. That's a hard lesson we all have learnt on the job trouble shooting double check from final destination I e spark no spark back through to sender/control system to relay and then fused link or wiring from source power. (Battery) until I see good v/amps then same as you done work through issues. But there's always a curve ball in there now and again. Most times its logic overload and brain shutdown. 😀 but got it done great job and keep it up
It's just so easy to have a module or a coil laying around for a quick test.
Great video,thanks for keeping it real.
I had a 90 f150 4.9 that did the same thing. It was the same connectors in the harness you were suspecting.
Twenty bucks says one of the caps are burnt in the ECM. Any 90's Ford truck with no-start or drive-ability issues and you should immediately suspect ECM, pull it; remove cover, and hone in on the three radial capacitors.
You owe me $20 :-)
Thanks Paul great fault finding procedure as normal, I would have gave up went home and spent a sleepless night racking my brains went back following morning dog tired and still missed the obvious! Just a thought would the vantage have a example of a good pip, spout or later SAW in its me memory? anyway many thanks sandy
Thanks for taking your time to explain and troubleshoot, your video has taught me a lot, I always wanted to be an auto mechanic but made other choices. I am 57 years of age and believe I don't have enough time to train and work as a mechanic. I always wanted to learn how to rebuild a transmission. Do you have any video on servicing transmission? Thanks, Mike
I do not, sorry. Transmission rebuilding is a specialty
@@ScannerDanner No worries. Thanks for your reply, and your excellent videos.
Love your videos you are a great teacher and class act to show you still get it wrong sometimes. Hopefully you can help me with a question I have. Same truck the condenser or whatever that thing is that's plugged in to the control side of the coil wire and mounted to the coil. Everybody says it's for radio noise. But that makes no sense to me considering where it's hooked into. Couldn't that short coil if it goes bad or wire arcs if broke?
Enjoyed the video. I own an'87 Ranger and this may be helpful to know about someday. Thumbs up Like!
Ozzstar Get a Actron CP9690 code tester. It checks live, record, graphing, transmission code testing, solenoid and relay tests, ABS, SRS, oil change maintenance light reset, and MORE!
Hi P Danner n thank you, yes it is a 1981 camaro 3.8 V6 a new motor was put in before i got it. I check the control wire at distributor and I have 8v and no control from the ICM, but when I disconnect the EST it jumps to 12v and I have control from the ICM.THANKS
Amazing work.
Im going thru one riht now and this is very helpful.
👍👍👍
Thank ..you...I'm trying to run one down now and with your help I might be able to sleep tonight...
I can help :-)
I traced it back to the relay ...now I dont have the fuel pumps coming on ...I have changed the relay and eliminated the inertia switch ..it has dual tanks and neither pump is coming on
@@markweber2958 Have you looked at your EEC Power Relay? This is notorious for problems and you will be missing power on a kinds of components under the hood and also power to your fuel pump relay, on the control side (winding side) of the relay
Two relays on the firewall both have power in and power out when key is turned on ...I have cleaned connections to pumps and sending units
Green connector is fuel pumps and brown connector is eec..I have changed both relays and cleaned up the connections there as well....could it be a bad ground on the selector and or pumps??
Thx u r the best...had same issue with 96 e350 7.5L ...ur a big help...
These trucks are everywhere in TN. My 88 is a 351w. Parts are cheap for these. I rebuilt the engine (first rebuild ever). It taught me a lot. Bad wires, bad grounds, everywhere lol I will probably never sell this truck. I rebuilt the C6 transmission too, but lets not go there LOL Know your limits! Ha! Ended up selling my Vantage ( a mistake) in the process and now have a Picoscope (love it). I have a newer F150 now, but I do like the older one. There's something about your first rebuild, the one that you cut your teeth on, that makes it hard to part with.
This is the first series of Ford EFI on trucks. Not the best, but it works. Might be a good candidate for MegaSquirt.
great job Paul
