    99 LS1: FPR or Fuel Press. Sensor?

    my dad took my T/A to someone to check my fuel pressure at the rail which was down to 25 psi when the motor revvs. It takes two turns of the key to start and drives like shit. I've replaced the fuel filter and pump and i'm looking for other things to rule out. A tech at the dealership said that my car doesn't have a FPR, but has a fuel pressure sensor in or around the pump assembly. the guy said that if it went bad, i could be getting low fuel pressure. Does anyone know anything about this?

    the regulator is in the fuel pump bucket above the pump area. is more like a return nozzle.
