Truck won't start?? - Pirate4x4.Com : 4x4 and Off-Road Forum

Mike Catts · 09-14-2005, 05:10 PM

81 Chevy 4X4, 305 motor, edelbrock carb. Ran fine this morning, went to start it this evening, started ok then back fired several times and died and won't re-start. Turns over fine and appears to be getting gas. Had no one else around to crank it to see if it was getting fire. I'm guessing maybe the coil went bad ut would like some other opinions before I haul all the tools up the hill and dig into it.
Thanks

See any gas pumping out the vent tube when you're cranking it? 99% of the time, a backfire will blow out the power valve. I'd check into this first. It's an easy fix with a carb manual and the new valve.

You say it appears to be getting gas.. So does that mean you could see it shooting in to the carb ?

If it's getting fuel then pull a plug and have somebody crank it over and check the spark.. If no spark then it could be the coil or the module in the distributor..

Go buy a multimeter and hook it up to the coil.
