Hey Guys,
1975 1.8 F.I. (Recently purchased)
I'll make it short...fuel pump isn't coming on, no voltage @ pump...so....I trace it as per (Bowlsby and my trusty F. I. Troubleshooting Manuel) and it says....check the dual relay located @ the driverside engine compartment.
And there to my amazement is this ratty looking "relay board" filled with mouse droppings etc. and I think, cool!! (IMG:style_emoticons/default/biggrin.gif) This I can fix..

as per all the info I found, there should be a small round relay plugged into position #3 for the fuel pump...and......there isn't? (IMG:style_emoticons/default/WTF.gif)

Only one in position #4? So....I pull it out, cleaned up the relay board,
(and I replaced the fuse, which was good)
and ordered a few round relays...
Now, can someone tell me, is the info I found, on multiple sites wrong? Should my FP run off relay #3? And since I bought a few spares, can I keep them in the other empty relay sockets there?

And does the voltage regulator relay have anything to do with this?

Good thing I kept it short huh? (IMG:style_emoticons/default/dry.gif)
Thanks...Terry.

Have someone turn the key to start while you are measuring voltage at pin 88d at the dual relay. If you have voltage here, then you need to check the ground at the fuel pump. If you have a solid 12volts at the wires of the fuel pump, then your pump is either seized or electrically open and it's time for a new pump.
