I posted up a few days ago and got to responses. My problem is that when i hit a bump the engine sputters. I got a few responses saying fuel pump and bad ground. Where should i start?

Any other suggestions? Maybe someone has ran across this problem before.

I would start with checking the wiring. Bad connections, loose wires, chafed wire insulation. Sounds like you could have a short or a loose wire. Could be in the ignition system, fuel system, or even in the main electrical distribution. Tracking electrical is like tracking a water leak. Good luck and hope it helps.
