    Fuel Pressure Test Results

    well i said i would post them so here they are...

    i arrived on site and went to relieve the system of pressure and there was 0 pressure in the system..so right away i knew somethin was wrong..i hooked up the pressure gauge and went to start the car..the car stumbled for a bit and eventually started..while the car was running the pressure was within specs..however when i turned the car off the pressure immediately dropped to 0

    i read that if it drops right to 0 then it is your pump..but the pump can be heard priming and working..also once the car is started it runs and drives just fine..so i'm not so sure it's the pump..any ideas??

    I replaced my FPR and I have the exact problem. My car has 100K on it so my guess would be my pump is dying. test your pump

    FPR. If it was the pump it would cut in and out while driving.
