Relay is good. No power to fuel pump., Now what?? Options

UPDATE: Self inflicted wounds are the worst. She's running.

So the other day when I was charging the battery, I knocked loose one of the 4 leads off of the positive terminal of the battery. I didn't know I had done it.

I am not sure what made me go check the battery, but as soon as I did, the wire dropped out.

Tom - I think that this is what your fuse box is for? Figures.

Thanks for all of your help.

Swapped in known good relay from headlight motor for fuel pump. No dice. No power to the fuel pump.

Fuses all look good. Going to replace the fuel pump one anyway.

Trans ground looks ok, but think I will double-check that.

Is there anything else I should be looking for?

Not sure if this is related, but a few weeks ago, my dash lights stopped lighting. The blinkers and idiot lights work, just not the illumination when the headlights are on.


I actually have some time this morning, and am going to try to diagnose my fuel pump issues.

Got a multi-meter, got some help to turn the key, and got a local VW store I can get a new pump or relay from.

So, which relay on the panel in the engine bay is for the fuel pump? I have a SirAndy Jumper in there (see his classic article).

Also, my multi-meter has ranges. Which setting should I use to test for power to the fuel pump?

Thanks in advance.

KG6DXN beat me to it. The Haynes manual shows the same configuration through 1973. I didn't see pictures for 74-76.

To check for voltage, set you multimeter to a scale that will read 12 volts DC, say 0-50 depending on the meter.

This also assumes that a PO didn't "improve" the wiring, my FP was jury rigged off another relay.
