Hey folks this is my first posting here and I will be grateful for any advice you have.
My 1991 Chevy 2500 pickup is sick. It was running fine until, It started missing and will not take fuel when you press the accelerator. I have some background working on engines but when it comes to diagnostics I am lost.
At the suggestion of some friends and others I have replaced the distributor,rotor,cap wires, plugs,ICV,throttle position sensor,fuel filter. What it is doing is lopping at idle and misses real bad when you accelerate. It is not flooding because there is no black smoke or raw gas smell. I have looked for wires that maybe broken or shorted and found nothing. It was running great until this problem started. It was a sudden problem. Do you think it could be the fuel pump or ? I am open for suggestions. Thanks
