[QUOTE="91svtcoupe, post: 15487993, member: 84794"] I didn't mention I have a fuel pressure gauge on the car via Aeroforce interceptor. pressure is steady at idle 39-40 but when going into a pull pressure drops, instead of rising, same symptoms as mentioned before still no wot pulls. installed the 2 340 pumps....today same situation again.... however I am only running one stock FPDM with a wire upgrade not a modified FPDM. will installing a second FPDM help?
