Good evening all, was driving around town and car stalled during the drive. Got the car parked and narrowed down the issue to the fuel pump not priming or turning on at all.
For starters: 1990 BNR32, Apexi ECU and Power FC, Deatschwerks fuel pump.
To sum up all the troubleshooting I've done:
Shot power for fuel pump relay and coupling to cap of tank, 12v of power is provided for a second, then relay shuts off providing no power. (while key is in on position)
Installed R33 GTR fuel pump and once again pump is not priming.
Fuses all intact.
Provided direct power to Deatschwerks fuel pump, pump did not turn on. (Gonna get a new pump)
Swapped batteries to a new one.
Any recommendations going forward to try and narrow down this electrical gremlin? Is there a fail safe where the relay will not provide constant power if a pump is not installed?
Thanks!
