Question about 1992 GMC Sierra K1500
I have no spark on my truck
Most likely cause of this problem on GM vehicles with a distributor, is the ignition module.
To replace the ignition module. Remove distributor cap and rotor. Remove the two screws that hold the module to the distributor. Once removed you will need to clean the surface of the distributor where the module was sitting. There will be a small packet of dielectric grease with the new module. Apply an even coating to the backside of the module (THIS IS VERY IMPORTANT). If you do not put it on the back of the module you will be buying a new module very shortly, as this one will burn up. Install module, distributor rotor and distributor cap. Plug in the module connector and start the vehicle. Hope this is helpful. Good luck.
