    Truck just quit on me

    Ok so I found the wire and unplugged it and tried again, now it is at 6° before TDC and running the same. I did get code 42 which is from unplugging that wire. I did take it for a test drive just a little way down the road and it was backfireing and poping like crazy at low RPM but ok at the...

    Truck just quit on me

    Ok we have a running truck, sort of, so it took a lot of luck, charm, or a lot of cussing, you pick but the truck started up. It blew a good amount of black smoke when I reved it up and would backfire, cough, and sputter then catch its self and be ok. Then all over again when I pumped the gas...

    Truck just quit on me

    So I did the steps to check my pickup coil and my ignition coil, as shown above from 1987 GMC Jimmy and it all checks out perfectly. While sitting in the engin bay fusterated and looking at my distributor cap for shits and giggles I checked for resistance on the center coil pin to the rotor...

    Truck just quit on me

    So I just got done checking my timing, checked the crank mark to where the distributor should be, that looked good, I decided to check it with a timing light, that’s where it got interesting. Now I’ve never messed around with a timing light much at all, like ever, but I was getting some very...

    Truck just quit on me

    Spark is a fat blue. I hope you guys don’t think I’m asking stupid questions, I’m not a great mechanic, but can usually figure stuff out, electrical stuff gets over my head kinda quick, an all I got is a Chilton manual.

    Truck just quit on me

    I haven’t gotten to check the cam chain yet but I did dump some gas down the throttle body and cranked the engin over, and nothing new still acts like it wants to start when I pump the throttle but won’t fire up. I have been confused while looking under my distributor rotor, what I have don’t...

    Truck just quit on me

    So it acts like it will start up, almost like an old carburetor truck would on a cold day, wants to fire but just never catches. Almost like it is the timing but how would it just change on me out of nowhere

    Truck just quit on me

    Pulled two of the plugs and they look fine, grey/white. Pulled my distributor cap, there is a little bit of deposits but nothing horrible, I pulled the ignition module and I’m going to replace that tomorrow. I’ll see if that works

    Truck just quit on me

    My ignition switch will turn to crank position, and dose not crank. As well it won’t spring back and won’t return all the way back to pull the key. I’m going to buy a new ignition switch tomorrow, and see if that fixes it.

    No code, and the light dose come on when i first turn on the ignition, the truck is all stock and I have not touched the timing, I have done almost all new cooling system, fuel system, and all the other stuff mentioned above, and I have ran at least 6-9 tanks of fuel sense.

    Truck studders / cuts out while accelerating

    I’m not trying to be rude but how will the clutch affect the engine stuttering, maybe I worded it wrong but its almost like it is cutting out. But if it seriously can be a clutch issue please educate me.

    Truck studders / cuts out while accelerating

    so recently my 87 v20 manual trans has been making a quick one time sometimes 3-4 studders while accelerating, always in 2nd or 3rd gear the truck was a quart and a half low on oil, I topped it off but still dose it, I’m wondering if maybe it’s one of my oil sensors, my oil gauge stays around...

    Weird sound

    Well I know I’ll have issues with getting my exhaust off so I was planning to replace with new headders and may run new pipes all the way out or just make a new y pipe and route to the existing exhaust, but wasn’t planning on doing it any time soon. I’m not sure on my rear main but it is wet...

    Weird sound

    So whenever I let the clutch out get going after the truck has sat a week or two I hear a weird whirling sound, after I’ve driven a while I don’t hear it any more. It dose it in forward and reverse, I’m thinking it’s the throw out bearing, but don’t hear anything when the truck is running and in...

    Truck won't start after sitting for years

    Clean the contacts on the distributor and check for spark, I would even give a few squirts of atf from a oil can into each cylinder to help build compression

    Who makes metal replacement radiators ?

    It was aluminum fin and plastic end caps, my only issue was that I wanted one without a trans cooler because mine is a stick, but it came with the tranny ports. Also I got a new radiator cap because the opening in the new radiator was narrower that the original brass one and wouldn’t let it...
