#155 of 195 same problem by bobpomeroy Dec 14, 2008 (4:10 pm)
but mine eventually fires. I think it has a bad sensor, but haven't gotten around to changing them. If your engine is computer driven, I think that's where you're heading eventually.

Replying to: amn81787 (Dec 14, 2008 3:51 pm) Check spark and fuel flow by pulling a plug and an injector. If you have both, I would check all the sensor leads to make sure they're properly connected.

Replying to: amn81787 (Dec 14, 2008 3:51 pm) You haven't mentioned the timeing belt.The truck is 12 years old.I would look at that.No matter what your sensors read.

Replying to: bullseye1 (Jan 10, 2009 7:00 am) Check connections for battery. At the battery, at the starter and the battery ground to engine.
#160 of 195 1986 Gmc S-15 2.8l WILL NOT START, HELP!!!! by metric1 Jan 12, 2009 (8:22 am)
86 Gmc s-15 2.8l 6 cyl 4x4   Hi everyone, any help you could offer would be more than greatly appreciated. I bought this truck over a month ago, so i am not super framiler with it yet, anyway it drove fine for the first 3 weeks of coarse, then one morning i went to the truck drove about 8 blocks could heard some squelling(which would happen for 20-30sec when truck started) the truck started to kick/jump as if it was running outta fuel, i put the accelerator down to keep it from stalling out, pulled over, it idled fine looked under the hood, nothing obviously out of the ordinary got back in when i tried to change from 1st to second again i lost power and had to hammer down the accelrator trying to get home drove sorta normal for about 8 blocks heading back, then started dying again and finally stalled out a block from home. After that could not start truck at all, engine just turns with no start, not even any kicking or combustion. Had a weak spark so replaced the wires coil, disct cap and rotor and plugs, so i have good spark to all 6 cylinders tested out good, there is fuel coming out of the tbi unit, i can hear the fuel pump start and i replaced the pump relay to make sure that was not of issue, i have not been able to start car with starting fluid or pouring gas in...running outta ideas here...if you have a suspesion or something i should check please let me know! Thanks alot! -Chris
