Engine Performance problem
1997 Dodge Ram V8 Four Wheel Drive Automatic
I was driving my truck and the engine just cut-out.
Had it towed home and started a diagnostic on it.
Performed the following:
Checked all fuses and relays all good with the exception of a 5A Illum. Fuse inside the dash (not sure what that is). Fuse is not blown, just no power to it.
Check coil: good
replaced distributor cap and rotor, checked spark plug wires and spark to each plug with a check light: all good
had a P0123 code on my scanner, TPS, replaced it and it didnt cure the problem. No more codes on scanner.
Tried testing for fuel injector trigger pulse: No light when inserting checklite probe from neg. Ground to one terminal. However, had light from checklite when connected to positive and one terminal. Cranked engine and test light blinked.
Also fuel pump makes no noise when ignition switch is turned to ON.
Do I have a fuel pump problem or a PCM problem?
have the same problem?
