1984 Chevy K10 starts rough, idles, then turns off when the gas pedal is pressed.

Question by Archer22 posted 6 months 1 week ago in Chevrolet

I'm working on my son's Chevy K10 and this is the current problem I'm having. The truck starts rough, but it will turn on and idle. As soon as I press the gas, the truck turns off. Any idea what this could be? I've replaced the flywheel, spark plugs, distributor caps, and some wires.
