1972 1.7 - Fuel pump not starting when key is turned, Problem with fuel pump Options

[itsmagic]

My 1972 1.7 914 recently decided to not start. I quickly noticed that the fuel pump is not running briefly like it should after the ignition key is turned. I verified that the relays on the relay board (Master, Fuel Pump, Blower) are all good by trying them on the headlight motors. I then verified that the two fuses on the relay board are good. Next, I popped the cap on the fuel pump relay and pressed it... the fuel pump runs when I do this. (The car will then start and run for a few seconds if I start it). Sooooo, I am at a loss... The fuel pump is fine, relay board is fine, relays are fine... what could be causing the fuel pump to not activate? Thank you for any advice. Wayne

To give a little more help, here is a more detailed explanation of how the fuel pump circuit works.
Sounds like your relays are good, however they still may not be making good contact in the relay sockets. Try spreading the male " prongs" slightly. this will make them fit tighter in the relay sockets. Turn them upside down and look at the prongs, they look like a round pie cut into 4 pieces. Spread very slightly. Also, if you have a very small wire brush, clean the relay sockets lightly.
The circuit for the fuel pump follows:
The ECU (computer) gets power when the power relay ( # 74) gets energized when the key switch is turned to ON. The power relay gives power ( pin #30 to pin #87 ) then via trace on the relay board to pin 86 of the fuel pump relay ( #75 ) and pin #1 of the 4 pin connector to the ECU. If the fuel pump relay is getting a ground from the ECU ( computer ), then the fuel pump relay will close ( energize ) and give power from fuel pump relay contacts 30 to 87, giving power to the fuel pump and the AAR via the traces to pin #12 of the 12 pin connector for the AAR and traces to pin #13 of the 14 pin connector for the fuel pump.
