SOURCE: I HAVE A 1991 GMC

If you are getting spark then it may be a fuel pump problem or fuel pump relay or inline fuse. Always start Fuel system troubleshooting by replacing the fuel filter or filters! You may be able to apply 12 volts from the battery (use a fused line) directly to the 12 volt side of the fuel pump and listen to see if the pump runs. Also may need to check that it is getting a good ground to the fuel pump. Then if the fuel pump does not run independently, replace the fuel pump. The fuel pump relay is computer controlled and several other things give the computer inputs which then controls the voltage to the fuel pump relay.

Was running and quit and will not start


check the distributor, mine did that and it was a bad distributor cap. Replace the button as well. Check for voltage coming from the coil first, use a voltmeter while someone flips the key to the start position/cycle.

Misfire on all cyl. Sometimes more sometimes less. all over the place


6 or 8 cyl ? Were you driving down the road when it happened ?

Usually the ignition module is inside the dist and that fires the coil. The coil is either in the cap or mounted on the intake manifold.
If the truck has over 100,000 miles the timing chain could be off. A timing light would tell you.

My 2003 gmc v6 just had its plugs and wires and distributor cap and button changed and i put the distributor button on wrong, it ran fine 4 a mon. or 2 and one of the screws came out of the button and...


The distributor cap and/or the ignition rotor most likely have a crack somewhere and the distributor cap should be replaced along with the ignition rotor. The ignition module could have been damaged as well as the ignition pick-up coil/stator and if replacing the distributor cap and ignition rotor does not solve the problem then the ignition module or the pick-up coil/stator assembly inside of the distributor is also most likely damaged and the distributor will need to be replaced. There is a certain procedure for removing and replacing the distributor, and the ignition timing is not adjustable and it is not set using a timing light or with the engine running, and if you do have to replace the distributor Let me know if you require the procedure to properly remove and replace the distributor or if you require any further assistance.
