Help! Help! Has anybody out there got a clear schematic of a 1973 1.7L relay board that you can share (the one in the Chilton shop manual is washed out and blurry)?
I need one to try and figure out why I am not getting power out of the relay board to the fuel pump. I have 12 volts to the power supply relay (new) and pins # 30 and # 85 on the fuel pump relay (new). I also have continuity from pin # 87 on the fuel pump relay to the fuel pump, so the problem seems to be something that's not happening in the pin # 86 circuit of the fuel pump relay, and, due to the terrible schematic I have, I can't locate the problem. Any help/suggestions would be greatly appreciated.
Here you go.

Sounds like the ECU isn't grounding pin 86 of the fuel pump relay. Double check that the ECU is getting power and that it is plugged into the four-pin connector on the relay board correctly.
