[QUOTE="mach1matt, post: 15813985, member: 182277"] Well, after messing with the car tonight I pulled the cpu and tried to replicate the problem. It in fact happened regardless of the cpu being connected or not. I found that the fuel pump relay is in the passenger side strut tower area under the maf sensor. That would explain why the relay plug under the seat had the black cap over it I guess. When I grab hold of the relay and twist it and the plug the pump turns on and off. I’m going to peel back the wrap on the harness and check for bare spots and replace the relay if I can find one. Sent from my iPhone using svtperformance.com [/QUOTE]
