hi. (72 1.7 FI). my fuel pump won't run. I've checked all the fuses, relays etc.
when I used an alternative power sourse (battery charger) to the fuel pump it works, so I know it's an electrical problem. Could it be in the actual ignition switch ??? Just looking for ideas, let me tell you I am really bad at electronics, so please keep answers so an normal ignorant person (myself) can understand. tks for your help. mike |

I would first do the follwing...after you rotate the fuses...
check with an ohm meter, or with a light bulb and some sets leads... check the wiring from the relay board to the fuel pump...if it is in the stock location, there is a gromet in the engine shelf that might be gone and the wires might be chaffed or cut... So check that set of wires first...the colors are the same on both ends... The next thing I would do, and have had to do...it get some of the spray type electrical cleaner...it is alchohol based... Get a clean tooth brush. Take off each connection at the relay board and at the FI brain and clean clean clean... Rich |
