So i thought i had problems with my fuel but everything is wired in correctly and the fuel pressure is set to 43psi. I started up my car, sounded beautiful. Stayed on and i was ready to go for a test drive..i step on the brakes and all of the sudden the car slowly dies. The car wouldnt start back up again. I cut off the switch to the fuel pump controller and it started back up. What is going on????
