Question about 1992 GMC Sierra K1500

2 Answers

1992 Siera k1500 4x4 Replaced rotor, distributor cap, fuel filter, wires, plugs. Will start but engine pulses and nearly kills. Is better when warm. When put in gear to drive, truck sputters and chokes and dies at each stop. When not in gear, engine revs like a champ. Any ideas.

You may want to inspect your vacuum hoses. Look for missing, brittle, or cut hoses and replace them.

I got 1992 Chevrolet C1500. Have changed plugs, wires, distributor cap and rotor button. Have also changed fuel filter. After it warms up it starts skipping and running ruff. What can I try now?


Sounds like throttle position sensor or mass air flo sensor.Both of these can be checked by hooking up to computer.You dont want to ramdomly start changing sensors can get costly.

Can't get 1992 Cutlass Siera to start,it tries to start,only for a second,and kind of backfires. Already replaced coil packs,plug wires, oxygen sensor,still does the same thing.I believe the engine has...


The mechanic should check on the ignition system first . Check the ignition switch, the ignition coil , the spark plug , the spark plug cable , the distributor assembly and the wires and the fuses.Check if there are worn out or destroyed then replace it. And then set the distributor timing mark and the firing order of the spark plug which is 1,3,4,2.These 1,3,4,2 are the number of the spark plug connecting to the distributor assembly.Then try to start the engine .The cause of the engine back fire is ignition timing not in order.
