Hey guys.....took a drive qand loving the 914 and stopped for a while and could not restart the car. I finally noticed there was no ful pump sound..(three port pump mounted by the steering rack. Checked the fuses, swapped out relays with new 914 rubber relays, and still nothing. If anyone wants to share an idea I am all ears. Fuel pump relaticely new...not the original one but identical. Thank you very much !!!

I would get out the trusty test light (or multimeter) and check for power at the pump. If you have power, then you know the pump is the problem,
If no power, first check the fuel pump fuse on the relay board. Then try grounding pin III on the relay board, with the key on (and the FI system plug pulled). If the pump runs then the problem is in the engine management and wiring. If not, then the problem is in the wiring between the relay board and the pump. Attached thumbnail(s) |
