Just the video I was looking for. Thank you
I been waiting 4 days for a mechanic to come over and replace my distributor on a 1990 k 1500. The mechanics had so many excuses. After watching this video it explains exactly how to DO it myself with confidence. Tks.again
I love this whole Playlist. I'm replacing about 75% of the parts covered in this Playlist and you guys have saved my butt big time. THANK YOU!!!!!
This is by far the best video for setting the ignition timing on an engine with a cam position sensor. I do not own a scanner that’s capable of getting a correct reading. I’ve used a timing light for years and it’s seems after watching you I can dust it off again. Thanks for being clear and safety minded while giving complete instructions for this process.
What an absolutely impeccable instructional video. Well done dude.
good job bud you showed what needed to be done and not a bunch of extra talking about nothing.... this helped a lot thanks
I’ve done this 4 or 5 times on various 88-98 chevys. I never pull a plug or get to tdc. I just pull the cap and make an index mark where the rotor is pointing. I pull the distributor and then drop in the new one and make sure the rotor points to that line. Then I unplug the wire under the dash and then time it up making sure to plug the wire back in. If I had timing chain issues then I’d do it your way.
Best instructional that I've viewed. Thank you for the clear views and stable camera.
Great video. On some models this vintage the ECM timing plug is under the hood to the right of the power distribution block on the firewall approx. beneath the passenger side windshield wiper. Also, if the timing light shows your not lined up with the TDC notch you can loosen the distributor hold down clamp enough so you can turn the distributor. Very slowly rotate it CW or CCW until the timing gun shows the mark lines up with the notch. Then tighten the clamp back down on the distributor again. It helps to have two people; one with the timing light watching while the other rotates the distributor until it lines up. You can do it yourself but it takes longer. Cheers.
i got a 92 Kodiak all the Commercial trucks with the early tbi its under the Glovebox easily accessible. i had alot of head scratching because the 1500-3500 GM chevy trucks its somewhere in the engine bay.
Appreciate a video that actually shows how to do it right...
I MUST OF DID ABOUT A 1K OF THE GM DISTRIBUTER BACK IN THE 70.'S.. LMAF. . THANK YOU. MY FIRST ELECTRONIC GM DISTRIBUTOR .
Thank you kindly, just knocked this project out with your help.
Great video! Very concise, accurate, user friendly instructor! I reallt love the step by step easy methodology!
Been a mechanic 40 years!very impressed!
Keep up the great work, and have subscribed to your channel!
By far the best, informative video I've seen.
Geeezzz this guy is damn good, because he made it soooooooooo informative n soooooooooo easy to understand everything...
N did it step by step as well, which I really appreciate n love too...
Thank u very much buddy...
Great step by step instructions
Very nicely done. Thank you!
Awesome video and explanation 👍🏼👍🏼 it has helped me a lot . Thank you 🙏
Hi. This was a great tutorial, thank you! I was putting a cap and rotor on my son's 87 Camaro IROC Z, and I noticed that under the rotor there was a lot of rust. I noticed there is no vacuum advance in this distributor, so I assume the ECM controls the timing advance. I noticed under the rotor that there were little triangles that I assume are for the advance. With all of this rust in there, I am wondering if the rust is stopping the timing from advancing?? It idles good, but shakes bad as it goes in the RPM range. Back when they had HEI distributors on Chevrolets, you could grab the rotor and turn it, and you could see the springs and weights move as you turned it. I couldn't get this one to turn at all. I'm not sure if it just doesn't turn, or if it didn't turn because there is rust in there. Any thoughts on this?
Great tutorial.
Thanks for the great video. Helped a ton. That crows foot is critical!
I have a 1987 Chevy g20 my service engine soon light is on. I did the obd1 paper clip test on it, no trouble codes. But the light is on. Can that effect my resetting the computer once pluging the wire back in?
If I have the distributor off timing? Would that cause fuel injector to not pulse? Put a new engine in now I have no pulse?
So, after removing the #1 Spark plug and setting it on compression stroke. are you suppose to set the crank pulley up with the 0 degree mark? thanks
It would line up automatically. The line on the damper and 0° mark would indicate top dead center. Which is the end of the compression stroke
Question, I reved my truck to about 5-6rpm and then it shut down on me , then I Rhode it home about 10mins running really roughly. Is it possible it can be my distributor any chance ?
thanks for share us with the replace . it really help me understand it . how to tim it and thank you very more. i like the video now
Thank you very much for refreshing my memory I should do that with the back of my hand now I got to watch RUclips I'm getting old and forgetting a couple of things
Nice thank you for sharing stay safe
Its a great video thanks for u help
When checking the timing with a light afterwards, is The notch on the pully supposed to line up with the mark on the block?
Yes. If it doesn't, you need to loosen the hold down screw on the base of the distributor just enough so that you can turn the distributor. Rotate the distributor until the timing line on the pulley lines up with the time notch. Then tighten the bolt on the distributor.
When you reconnect the pcm what happened if it changes your zero.
My buddy blew one of my motors (built 306) because he forgot to put the oil pressure rod (sbf) in before the distributor, and within 10mins of the motor running with no oil pressure, we started hearing a loud screech. I ended up buying a 331 stroker from his buddy and it was the best investment I ever made. Moral of story, everything happens for a reason lol
+ucnhtmenow1 Thanks for watching our video! 1aau.to/m/Shop-TRQ
If I hear veerickle one more time...
Would rpm jumping around when first starting up cold and low rpm causing it to die after reaching operating temperature, be the pick up coil in the distributor ?
That was the problem with mine I have a 95 with the 350
Nice Video very helpful
I replaced the distributor on my 90 k1500 with another used one because my old one was squealing like a pig. the truck has never run right since. I have been trying to figure why for a while now and have replaced just about every sensor and tune up part I can think of, some more than once. with no luck truck starts and runs but stumbles and misses at all rpm. I can drive it but its no fun. I just noticed while looking at another ad for distributors that there may be a difference between a87-91 and a 92 up distributor. can any of you guys school me on this. I may have bought one for a 92 up, dose it matter?
Dude u created the perfect how to vidieo
Why didn't you show the crank turning procedure for TDC? Not mentioning that by yourself is a complete bear to turn and feel compression on
What if my distributor that flat line u line up with firewall what if not lined up like yours. Bought this off someone who did it on his own
My 98 Tahoe has this same looking motor installed in. Does it mean that motor is changed? I noticed this today cause I started to change wires etc and have wrong spare parts..
no. its the 5.7 vortec.. used in sieras, silverado, tahoe, suburban..
Uh oh. I am in the process of replacing intake manifold gaskets. I didn’t watch this video beforehand. I had to remove distributor to get intake manifolds off. All I did was mark the cap and a bracket to line up. I did spin the gear to clean some goop off it. Timing ..... who knows now. Can this process be done with distributor out? Get cyl 1 to tdc. The rotate rotor to wire 1?. That will get timing close enough to run and set accurately? Great vid.
yes
Best video
+Oak Cliff Thanks for the feedback! 1aau.to/m/Shop-TRQ
88 to 02, do you mean 87,88-95?
I have my 94 Blazer 5.7 on TDC and trying to put in the new distributor but the rotor will not line up w cylinder 1. It will only go all the way down when pointing to 2. It seems the distributor will on go down into the block one way. Is this correct?
I like cars more than I know about them. what good comes out of changing this part?
Vehicle will run smoother in general under idle or under load. Lots of times the distributor or distributor cap gets corroded over the years which causes poor voltage and amperage which will cause vehicle to run rough or no start. All it’s doing is converting mechanical energy to Electrical energy
Gmc vandura 1993 will this diagram help
I got a 1989 Chevy there hard to get them out sometimes
Thanks
Crazy cuz the gasket I keep getting from autozone and orielys never work or fit
What if the line is not on zero?
I have a 1989 chevrolet k2500 with a 350. I set my timing mark on the crank an distributor is set pointed at #1. Put it all back together. Went to set the timing up an I have a flat spot on distributor advance or retard. My question is do I move the distributor 1 tooth back or forward to get over the flat spot? It idles to low retarded were it's close the timing mark on the crank mark. Any help
I changed just the cap and rotor and the truck didn't turn on after. Also did spark plugs and wires gas was in the sparkplugs. A few of them. I still continued. Followed 1 by 1. Rotor was place the same way it came off. Any thoughts?
If it cranked and didn't start and the plugs were wet with fuel you have no spark. It's either the distributor pick up coil, or the ignition module has failed. Usually it's the module, but if the distributor is looking old and worn replace it.
Also, If it didn't try to crank, it might be hydrolocked
Can you do mine please
How are you doing? My name is Wilfredo I have a little problem I have a 91 GMC, sierra C 1500 Rear Wheel Dr., 5.7 L and add call start I have a little backfiring through the exhaust for like a half a second then it runs beautiful after that like normal that just started happening. I covered all my ground cleaned up everything to the fullest change the distributor, cap rotor, ignition module cables, spark, plugs coil air filter, clean ground to chassis to block to brackets change the heat sending unit change the heat temperature sensor used carburetor cleaner to clean out any gunk in the carburetor. It looks exactly like your motor on your truck and change the fuel filter. I waited to the tank was completely empty. Used a bottle of Lucas fuel injection cleaner filled tank to as capacity and still have that little backfiring. It starts right up one shot but immediately it starts rumbling a little backfiring here and there then it goes back to normal on his own dries excellent on highway everything can you help me with this and tell me more or less what could it be? Thank you.
What size is the crows foot tool?
9/16 or 14mm
Those distributors must be put back like they were , the oil groove above the gear must be clocked correctly or oil will not get to lifters on both sides
What is that black marker mark for ?
My veerical blew up when I did this
My timing wire is in the drivers side engine bay.
Eveything was goin good..till i wemt to start it up n now it wont crank
It wasnt on tje compression stroke id bet.
This dude is trolling 🤣 veericol

How to gofroma1996distributer to a1984 distriutor
He keeps saying vre-hicle. I thought it was a stutter the first time, but after the 3rd time I was like wth..
👍
I always did tdc by ear. You'll hear the pressure blow out of the plug hole like a mini compressor.
You never disconnected the timing advance wire. So you're timing is incorrect.

Great Video but you must remember that the oil shaft may be in the wrong place because all the distributors are not the same and a lot of people do not have the shaft turning tool you may be able to set the shaft down in the block at top dead center and slowly rotate crank and it should drop in to place on oil drive shaft it won't take out of time then adjust the distributor after ran.
You're so right! Having a hell of a time trying to get the rotor to line up w cyc 1.
Distributor was a headache for the mechanics: thanks to O B D 11 , and O B D 111
I did the steps in the video and no my vehicle won’t start
....."verhicle"?
“Vericle”
Its not easy to access, esp for a big guy like me. Where are you sitting, where are your feet...? 🧘
1988-1995* This instruction video WILL NOT work on vortec models. The timing is set with a scan tool doing a cam crank relearn. Not near as simple as unplugging computer override and turning the distrubutor
Your fingers are way too close to that cooling fan when it's running... Careful!

96 to 99 are different to a point. Timing is different. Can't use a gun.

Way to put the duct tape on off camera
This is not how it's done on my 98 5.7
+Jesse Rousseau We appreciate the feedback. Sometimes there are multiple ways to accomplish the same repair. 1aau.to/m/Shop-TRQ
...that's because your '98 isn't TBI injection like this one..it is the 5.7 "Vortec"..different intake/injection system, different type distributor..IMHO, a sh@ttier distributor design than the one on these TBI engines...'96-up were "Vortecs"...
Yeah, the later models were totally different. I've done my 98 and my dads 2000.
