Have a 1994 3500 Auto cummins. Nothing done major just exhuast and was told it has #0 fuel plate/afc tuned. Well just started the other day but truck acts like it has dead pedel, truck has no power. Im thinking maybe bad fuel pump(low fuel pressure). Anything else it could be or what I need to check for? Going to work on truck today to see if I can figure something out.

Thanks

 

id check fuel pressure first

 

Fixed it, put a bhaf on yesterday and drined some fuel out of fuel filter and trucks running perfect!! thanks

 

I HAD TO SAME THING GOING ON WITH MY TRUCK
BUT IT WAS THE LINE GOING TO THE BOOST GAGE HAD A HOLE IN IT
