[QUOTE="Yellow98SVT, post: 10248703, member: 10702"] I finally got around to putting a fuel pressure gauge on it and it showed 12 psi at idle. I know at idle it should be at least 35 psi. When you blip the throttle, the pressure drops on the gauge needle instead of increasing. It will idle and support about 15% engine load and no more. Anymore than that and it starts to buck and fart and spit. Here's the strange part...it will start and idle on the stock tune; however, with the blower tune it wont even crank. Tim did the tune and it ran rock solid for 10 months, so, no problem there. The only think more depressing than a 100 dollar fuel pump killing my engine would be a 10 dollar fuel filter. I cant imagine what it could be other than fuel delivery [/QUOTE]
