98 dodge ram 1500 5.9L 2wd. Truck runs really rough, stalls, then won't start. No check engine light now. Had misfire codes, did tune up, now it still stalls and no check engine light.


What is the O2 sensor reading? If it runs rough check the engine compression, run an injector flow test and clean and replace as necessary. Check the EGR for leakage. Drive it and see if the misfire codes return, I think they will.

Whats the pproblem if my gmc yukon xl check engine light blinking


That usually refers to the vehicles computer detecting multiple misfire codes. Does the truck run rough? If it is flashing I would not drive the truck because you risk destroying your catalytic converter or worse. I would get the truck scanned to see what codes appear and then go from there.

ever tune it up,?
carb engine, or EFI?
the tacho action tells you the primary ingition side is failing.
the jumper is inserted, in the EFI , code 8 is spark misfire.
jumper the service check connector , 2 pins.
code 8 can clear fast, so you make engine mistfire, watching the lamp. but is only more evidence that the the ECU can not fire the coil.
The Tacho proves that. if the code 4 or 9 show up, bingo.
drive with the jumper planted.
see page 6-96 in the FSM book.
