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.
