On wed. My 914 after i put gas in her the fuel pump stopped working. I had her towed back home. Today I wired a direct line from the battery to the pump and the pump works perfectly. I have been doing some searches and i have found some post. and diagrams. I have also changed the relay fuse still to power to pump. Where does the relay board gets its power from what wires.

I Finally got my fuel pump working i did the following

"Take out relay #75. Make sure that pins #30 and #85 have 12v.
If both have 12v, jumper pins 30 and 87, and see if the pump runs.
If that works, put the relay back in and ground the front left pin on the 4 pin connector on the relay board (numbered III on the diagram). The pump should run." Thanks ChrisNPDrider

I did all this and the pump worked (IMG:style_emoticons/default/biggrin.gif) but once I would plugged back the front left pin on the 4 pin connector on the relay board (numbered III on the diagram) it would not work. So it was a grounding problem. I was able to trace the wire to the grounding point and it was loose I plugged it back it and it was fixed.

But now after i changed all the plugs and a new pertronix it does not want to start it was starting before.... I think it is the pertronix...

If you cross the wires, they will fry instantly ...
