Hi guys,
I have a 94 3.0 that just quit running while I drove over a speed bump at low speed. We have done extensive work Ignition Module, computer, distributor, checked some relays, checked fuel pump, oil pressure, coil, tuned it etc. Crazy thing is, after working on it one day it started, ran for 30 minutes with the hood open, when we shut the hood, it quit again. I am totally puzzled. No fuses are blown. It's like a jarring or vibration causes the engine to kill. Right now it WILL NOT START.
Please help, Any suggestion or similar experience would be awesome.
Thanks,
Big Al

 

Weve have changed everything I can think of. It actually has run 3 or 4 times since the first incident.
Thanks,
Al
