Engine Mechanical problem
1984 GMC C2500 V8 Two Wheel Drive Automatic 100000 miles
I am a little stumped here. I was driving to work one morning at about 60mph and the truck just dies. I pulled a couple plug wires and turned it over. I had what I thought was a decent enough spark and fuel shooting into the carburator while I was cranking. Still nothing; no backfire. Nothing. A month prior I was having a slight misfire issue and I installed new plugs, wires, rotor, cap, coil, and ignition module and the misfire issue had been resolved. Now all of a sudden this happens. I pulled it back to my barn and poured some fuel in the carburator and turned it over a few more times. Still nothing. The fuel seemed to be spurting up out of the carb while I was performing this test. Double checked spark. Still good. I have not performed a compression check yet, just because I thought even if I had 1, 2, 3 or even 4 cylinders bad, I should still get some type of fire. No oil leaks or water in oil etc. Good voltage at distributor, pick-up coil about 850 ohms. All I can think is that maybe my spark isn't strong enough (seems like at least one cylinder would try to light off though). Or I somehow managed to jump timing like 180 degrees? I am little lost, any idea where I should start. I still have my old ignition coil, I could slap that one back in and try it?
have the same problem?
