Finally someone who's smart enough to explain this I've been searching and looking for almost a decade now reason being I don't know anything about dodge and my brother was in a fatal accident that ended up with him and three others loosing there life and his trucks the only thing I have left and it ended up losing its life with them (it flipped into a fish hatchery) yes it's sad but life goes on and I've been trying to repair it so I can at least have that to remember him/them by thank you so much I can't explain how much appreciation I have for you now
I have read so many comments some are for appreciation some for dislikes and so on but nothing out of the common, but I never want to read these comments like this one because it hurts only by reading it, I put my self in your place and then I can relize how hard is this and all you have gone through, IM so sorry and hope the best of this life for you and your Beautiful Family as well.your Brother and The other people may rest in peace.
@@JM-AUTO hopefully now I can finally get the truck running if I ever do I definitely will treasure it I know it'll definitely help open up a lot of opportunities for me and my family I just don't trust people enough to let them work on it even if they're certified you know
Muchísimas gracias mi amigo de lo agradezco demasiado mi compa. And also your English is very good buddy 👍 soy mexicano tambian mi compa pero nunca a ido para México pero que tenga un bien dia y de la pase agusto. Sale thank you vato.
im glad you liked the video and thanks for visiting my channel.
Hi 2001 dodge ram 1500 5.9 L 4x4
Random stall out at idle, got stranded idling in parking lot at work, thought it was fuel pump becuase would crank no start, banged on pump would start with stepping on gas , would idle perfectly fine.
Driving home dies again, I repeat to see how far I go, down the block from home I start to push cuz it woundnt start, I let cool off and it starts.
1 week later I turn it on first try and start (didn’t drive it though), replaced fuel pump (I can hear it when key in ON).stayed idling for 29 minutes. Then dyed.
Sometimes it start sometimes it doesn’t, oil pressure good, battery good, Ac perfect, tested all fuses( not relays) can’t find fuel pump fuse.
With light tester, Took off and Tested ignition coil read fine. Took off coil connected to spark plug and was fine.
Thinking bad pick up sensor that’s under distributer?
Has code P0505 for IAC but I replaced it a year ago and it’s still had code but never stalled until now. Could it be bad PCM?
if spark, fuel, air and compression is fine you might have a bad pcm but if you have access to a scanner that has that ability to read live data then you should see what is happening when engine is running and get freeze frame data even if there is no check engine light. but if you have spark, fuel and, air and compression then the engine should start so eliminate one by one so you can determine what the problem is. thanks for sharing
Mine does the same thing. If I leave the house I gotta have the truck running cause if I turn it off it dies until it cools off. It just started last week
Brass distributor caps and the more expensive brass rotor last a lot longer. I try to only use the better cap and wires on mine because it's such a pain to get to on these engines. And dielectric grease on the contacts so they don't corrode. I just use the stock Champion plugs because I've used the expensive ones before, and I noticed no difference except the price.
The stock champion plugs are the best choice for these 3.9 5.2 and 5.9s
Good video. Appreciate you're help
No problem 👍 and thanks for sharing
Thanks I’ll try this. My 96 dodge 1500 cranks but won’t start too. I need to buy one of those tester things you got.
great, thanks for sharing and for visiting this channel.
Thank you for the step by step demonstration on what and how to check for spark 👍. Good job and God bless. ✌️.
thank you I appreciate it.
Excellent work amigo.
Thank you very much! and God bless you.
Thanks for the help. God bless you too
You are so welcome.
I have a 5.2 Dodge, looking for answers, yesterday I replaced the distributor cap rotor, the coil oh, and the crankshaft sensor I still have no spark? Some say the plugs and wires Maybe and on some blogs they say it could be the computer?
thanks for sharing, im a fan of diagnising the problem first before replacing, have you checked for spark coming out of every ignition component? have you checked the electrical part of the ignition system components, if it would be the pcm or crank sensor then you also dont have fuel, do you have a spark tester to check what component is firing and which one is not? do that and let me know.
@@JM-AUTO yes I have a spark tester, tested at the distributor first replaced it then tested at the coil no spark there either, replaced it , thought the wires might be bad so replace them still no Spark, replaced the crankshaft sensor, also I sprayed ether in the carburetor while cranking so if there was any fire at all it would have tried to start, one clue I was told about the computer is when you turn the key to the on position if you don't see a check engine light and I don't see one when I turn it on
Wow enter net is crazy. I'm working on one as we speak trying to figure out the problem rite now.
@@danmichansHey bud ever figure out the problem? Mine was running like a demon. Didn’t start it for two weeks and now I don’t have spark. These trucks have so many electrical issues in my opinion.
@@dman4305 Yes, I replaced the computer and it fired right up , got spark!
I stg my truck died on the side of the highway 1 week ago and this is a HUGE MF help dude I’m checking the ignition coil rn
thanks for the time on the channel and for your comment, im sure you will find a solution to your issue on your truck.
This is a common problem with Dodge/Jeep Dakota's, Rams, Wranglers. Random crank/no start and stalling suddenly. I've seen people replace the coil, cap/rotor, camshaft and crankshaft sensor, fuel pump and finally PCM. No one has the right answer on why this happens. A vehicle that suddenly stops at highway speeds is dangerous and their should be a massive lawsuit. When the vehicle doesn't want to start, gauges are dead. Then later on gauges come alive and vehicle starts
on this video the the distributor cap was the problem, til today truck is running so smoothly.
9:03/10:21 This video was very helpful.Did a good job explaining everything. Thank you and God bless.😊
I am getting a crank no start on 98 dodge ram 1500 with 5.2. I am not getting the spark at the coil. Can you tell me if when you were cranking ...didthe tach needle moves? Im pretty sure I have a bad crank position sensor, but cant be sure. If Im reading right, the tach needle should move when cracking if crank position sensor works. Can you confirm that please? Also, i removed the connector on the bottom of the coil to check it for voltage. It was there, but now....when I try to push it back on, that connector wont lock. Not sure why though.
the tach gauge wont move if crank sensor is bad,.
Where would you put starter fluid when testing to see if it’s a fuel issue in the little hole or in the throttle body
in throttle body but it is dagerous if putting too much, instead if you want you can pull out an injector to see if engine is receiving fuel.
The intake
@@brittanydunn2638 in the intakeor in the nearest hose in the intake so the fuel can make it to the throttle body, it is not recommended, better to take out an injector to see if fuel is getting to the engine see the spark plug if it is wet with fuel and also smels fuel.
Very good video..God bless you too...
thanks for your comment I really appreciated.
Really nice video 👍👍👍 thank you
Hey buddy, not sure if you reply often
Long story short lost my brother he had 98 ram with 318 engine. I got it running, and I figured I would change spark plugs distributor cap wires and rotor.
I changed everything and now my truck barely turns over ( only if you press throttle down ) and it runs very rough. Shuts down if you let off gas, and the belt is squeeking and wasn’t before.
I ended up putting old distributor cap back on, old rotor back on, and I even took out plugs and gapped them correctly. Truck will not run and runs rough. I really don’t know what to do now..
Sorry for the lost really sorry, see if the firing order is correct.
@@JM-AUTO I checked it 3 times and was right I just can’t figure it out
I just did this on a 2001 dodge Dakota 3.9L. I put a cam sensor and crank sensor. The crank sensor and the cam sensor inside the distributor work together so the PCM will send spark to the distributor then to the spark plugs.
im glad you did a great job in my case the problem was the distributor cap did not need to replace any thing else and the igniter sends spark to the distributor and the ditributor to the spark plugs if the pcm sees tha every thing is fine, thanks for commenting on my channel and stay bless.
I have a 3.9 in my 92 DodgeVan.No spark.replaced the Coil an Crank sensor was no help.This may be my problem as well..thanks Big Dog Dailey...
@@JM-AUTO I have that same truck with the same engine , 5.2 liter. As a matter fact , I have the same exact problem right now. I need to buy the tester. What do you call it?
It is called spark tester, thanks for visiting this channel.
Mine seems like it has fuel. No start with starting fluid. Fuel sprays out of the relief valve on the rail. Replaced the TPS. Cranks good, but no start still. Ran earlier in the day. Dies at idle. Now won’t start
I am currently experiencing identical issues with my '97 2500 Dodge van did you ever figure out what your problem was?
LOL, that's not how a spark tester works. You cannot leave one end not connected to anything or you will see nothing.
on my 92 DodgeVan 3.9 i have no spark to the new coil.The GREEN wire going onto the coil is hot when key is on.. The WHITE wire flash as engine is running.No power to this plug in.. Where dose the green wire start? The key trurned on maybe???
the darkgreen/orange wire is the +b from the asd relay and goes to pin 57 on the engine controller(pcm) if every thing is ok with the crankshaft position sensor the engine controller will ativate the asd relay so the asd relay will energize the ignition coil on wire darkgreen/orange. the gray wire is the coil driver and it goes to pin 19 on the engine controller. if engine controller does not receive signal from crankshaft sensor it will disable ignition coil and fuel pump.
What is the first component with the electrical connector called
ignition coil
@@JM-AUTOI have no spark there either.
I ordered a new ignition coil pack hopefully this solves my crank no spark no start issue.
I see you had spark there but I did not . I think the ignition coil generates the sparks and pushes it through the wires to the distributor to the engine right?
Gracias por tu video
Just the cap was the problem ?
yes problem was the cap only
hey so i had the fuel pump on my 96 ram replaced and it ran one day and then the next day it would crank but no start and had someone take a look at it they poured fuel down the throttle body it started for few seconds and then died what do you think it could be?
what engine do you have 5.2 or 5.9, do you hear the fuel p when turn ignition on? if you dont hear the fuel p check fuse and relay for the fuel p, if the truck starts when you spray stater fluid then there is no need to check the ASD relay. it depends on what symptoms you getting you might have to bring down the fuel tank again to directly check the 4 wires that connect to the fuel p to see if it is getting power and ground, if every thing checks out good with the wires the you have a bad fuel p but first check fuse and relay.
@@JM-AUTO i have a 5.2 I've tried starter fluid but it barely starts the truck and the person told me im not getting fuel to engine so what would they be? cause im thinking it's getting spark cause gas poured down throttle started it for a few seconds and died could it be crank sensor?
@@JM-AUTO the relays are ok so im kinda stuck cause i don't really know what it could be
@@JM-AUTO and i hear the fuel pump also engaging when I turn the key
@@Fnhfendi the truck should start 100% aleast for few seconds when you spray starter f but if it makes no difference with and without starter f then you might be missing fuel, take out one of the spark plugs that it is easy to access and see if it smell gas if it does you are getting fuel if it does not smell fuel you not getting fuel, also hit the fuel tank with a hammer or some thing like that from beneath at the same time some one else is cranking the engine, if you want to keep me updated and I'll try to help you.
So helpful and clearly explained. Gracias!
thank you, your comment is very appreciated.
hey JMAutoRepairnum1 where are you located? In Long Island or in NJ?
excellent job diagnosing. Very smart work
Thank you very much! I really appreciate it.
Aver si es eso con ma mia hace lo mismo only çranks
ojala y q sea eso Amigo, lo mas conveniente es hacer los examenes primero, gracias por compartir.
Good video. Had a neighbor vomw over and chat with me so didn't get to even finish the video, but swapped an old distributor cap after noticing the center stud was rather warn & she popped right off!
thanks for sharing very appreciated.
Very Great thanks. Jesus loves you :)
thank you for visiting my channel that is very appreciate it.
Not sure how true it is but i heard that you can show getting spark out of the coil but it sometimes isn't enough spark to be efficient. I assume just change the coil too
TRUE, that happens some times, thanks for visiting this channel.
Thanks
thanks for coming to my channel, really I appreciated.
Does it say NO BUS. Flashing in the odometer??
If it does it is a faulty crankshaft positioning sensor. It is located in top.of bell housing. Hope this helps
no this was a different issue, there was no spark fromp the distribuitor to the spark plugs. thanks for visiting my channel.
great video
Glad you enjoyed it and thanks for watching
Maestro como se llama este tester. Por favor.
12 volt power probe tester/ testiedor de 12 voltios, gracias por compartir.
@@JM-AUTO muchas gracias, Dios lo bendiga grandemente
Thanks. Just found my router contact at a 45 degree. Plastic wore out and the coil to distribute completely black. Helped huge
im glad, thanks for visiting my channel.
Great job primo,and thanks for taking the time to explain this to us,god bless have a nice day
Glad you enjoyed it, and thanks for taking the time on this channel.
I'm definitely trying this tomorrow on my 95 Dakota. Great trouble shooting technique.
thanks for visiting my channel, hopefully it works for you.
Awesome job man. I appreciate this. I will try on my truck tomorrow
Glad it helped, thank you
Ima try this on my. 5.9 Dakota
Mine is doing the same thing can u please help
What have you done so far?
Awesome, the secret is revealed. Great job! Great use off your camera!
thanks I appreciate it and also thanks again for the visit.

Would this send an engine code
some times it does, some times it doen't.
Very good step by step video looking forward to more videos
thanks for visiting this channel appreciate it very much.
I changed my fuel pump, fuel pump relay, starter, and spark plugs on my 1997 dodge ram 1500 5.9 magnum and she still wont start. The gas gauge is not working either i ran out of options of what it might be, would any one know what the problem is?
have you test for spark, fuel and fuses?
@@JM-AUTO when u mean spark could it be the distributor because i recently trew in new spark plugs bearly got 4,000 miles. All my lines are good i also dont hear the fuel pump turn on but all harmess are plugged in right
I got a crankshaft positioning sensor im going to trow on and see if that could one of the issue
@@JM-AUTO also my fuel rail does not have a shader valve to see if fuel comes out, is there any other way to test fuel pressure?
Can you pull out an injector and turn on ignition switch so you can see if the engine is getting fuel.
Que dios te bendiga hermano
igualmente a ti tambien
Gracias hermano igualamente
deveras muchas gracias.
I have a 97 ram 1500 5.2l I changed the distributor cap n rotor. distributor pickup sensor and spark plugs and brand new fuel pump new camshaft position sensor new asd relay and fuel plump relay but the pump has no power when key is turned. So I jump the fuel pump Relay to come on but all it does is cranks no start I been fighting this for 1week I have given up any suggestions ? (Also when the Engine was cold it use to lose power and back fire when driving it)
aways test before replacing any componet, have you scanned the truck for any trouble codes? about crankshaft position sensor, throttle position sensor, compression test, or a bad pcm? now with a bad crank sensor the truck will never start even with a bad throttle posion sensor the truck will have difficulties to start or it will not start at all. check those items and let me know.
Same here../2002 ram1500 5.9 not Disel..
And change the same and still doing the same....have you fix yours Dee?
@@ElGordito85 yeah it had a bad PCM got a new one and everything works fine now
@@ElGordito85 yes that was a few months ago and the distribuitor cap was the problem, it is best to check what the truck is missing so you can replace the part that really needs to be replaced.
I xk no lo dise en español
Todos mis videos tambien estan en español en mi canal en español incluyendo Este video
Test crank sensor
im glad you did a great job. in my case I diagnosed the problem and the problem was the distributor cap, the distributor was good and the pcm sends signal or spark to the igniter and the igniter sends spark to the distributor if every thing else is fine. thanks for your comment and God bless you and your family as well.
nice info and ideo
thank you very much for such a beautiful comment
Beautiful
