Guide :Maintenance & Repair : 1994 Chevrolet C/K 3500 Crew Cab 2WD
Truck starts, idles high, then dies
Hi John! I'm hoping to get your sound advice and recommendations regarding my issue. I have a '94 Chevy C3500 with the 7.4L motor. It was running fine until, one day, I stomped on it and noticed that it hiccuped. When I got home, I changed the plugs, wires, cap and rotor. When I tried to start it up after these changes, it wouldn't immediately start. When it does start (it tries to turn over a few times), the idle jumps to over 1,000RPM and then it dies out. Also, I noticed that the fuel pump is louder than it's ever been. Please help me. Thank you.
