okay so i was home for a total of 10 minutes today, tried starting the car again and listened to see if the pump primed, when i turn the key to the on position it doesnt do anything, when i crank the car i think i hear it pumping, but as soon as i stop cranking the motor i hear the pump prime? since its priming shouldnt the mpi and fuel relay still be good?
