I have a '73 914 2.0 with a well sorted D-jet system. Driving the other day, I came to a stop and the engine died. When I tried to restart it, I didn't hear the fuel pump cycle when the key was turned. Sure enough, when I checked with the multimeter, no voltage to the pump when the key was turned. I had previously relocated the fuel pump to the front, extending the power lead from the rear to the front through the center tunnel.

Troubleshooting so far: 12v directly to the pump shows it running fine, correct continuity from the rear to the front on the power lead, replaced the relay. As far as I can determine, the problem lies between the circuit board and the original 12v lead. I had previously replace the circuit board and both multi-pin connectors. The ground point for both the circuit board and the fuel pump are perfect. I replaced the ignition switch a few months ago as well

Is there another common failure point that I can investigate?

Its been a minute since Ive worked on a 914, these have a double fuel pump relay don't they? Did you try wiggling, tapping, or replacing that? My buddies 914 had one and it was prone to cracking every winter and resulting in a similar situation.

Someone just sent me a very detailed troubleshooting checklist from Jeff Bowlsby. It its a pin-out to pin-out process that should do the trick. Just what I was looking for.
