    Would crank but no start...now no crank no start

    The first problem was engine cut off while driving. Towed it and ran codes. Only code was the permanent P0420 that has been there for 2 years car ran fine. Replaced high pressure fuel pump and fuel pump relay. I will have to wait a bit for the in tank fuel pump. Tried to start again, cranked...

    Fuel Pump cutting in and out.

    Hi everyone! Most issues with my SHO I can solve with some searching these forums, but this one is beyond me. The car has a bit of a stutter at low RPM but is still drivable. I have just been telling myself that this is due to there being oil in the spark plug wells and I will fix this when I...

    Engine bog

    Hi, I just purchased my first SHO (89 5spd) last year from someone who let it sit in the sun the last 10 years. Admittedly, the engine has less than 40k miles, and the rest of the car less than 80 (towed behind a camper). After a bunch of new parts were put into it (including a new fuel pump)...

    My 93 ATX quit Friday while I was driving and wouldn't restart (cranked fine). Verified inertia switch in trunk not tripped (open) - cranked, but still no run, so towed home. No CEL; No Codes, but noticed that with KO, I did not hear the fuel pump come on to charge the fuel injection system...so...

    Crank but no start- Fuel Pump circuit? PATS? Please help with ideas

    Been off the forums for a while, but here's the situation: '97, currently will not fire but will crank over. The theft light is blinking regularly as soon as the ignition is turned to run, it goes off in about 45sec to a minute with no coded blinks. I just replaced the fuel pump since I...

    Problems after long idle

    I have a strange problem that's recently popped up. I tow my '91 SHO behind vehicles that I deliver, then I unhook my car and drive it home. I tow it with the engine idling, because if I don't, I have to replace the rack & pinion about once a year, and that got old real fast. This was all fine...
