ok i was doin some datalogging last night with my diablosport and my FRP which i am guessin is my fuel pressure drops from 39-40 psi which is where it normally runs all the way down to 1,2,3 and at one point 0 psi. im thinkin fuel pump but any other ideas would be great.

Could be pump yes. There is also a Fuel Rail Pressure sensor that could be going bad, just happened to me after installed my vortech.

Does the car run when the fuel pressure is that low? If yes, the sensor is bad. If no, the pump may be dead.
