So my fuel pump doesn't turn on now. I switched it out for another one from a parts car (which I tested on a battery outside of the car and it worked fine) but it didnt work either.

When I put the key to the "ON" position, I don't even hear it whine. I swapped on a Holley blue pump I wanted to use...which is noisy enough to hear when it's on - same results, no power.

I checked my fuses, but they were all good. Could this be a ground issue and if so, where does the FB fuel pump ground? I'll probably just hot-wire the pump this weekend anyways, but I thought I'd ask here first since I like keeping things factory for wiring when possible.

-Thanks!

 

What year is the car?

If your trailing ignitor dies on the later FBs(I know 84 & 85) you will lose power to your fuel pump.

Check to see if your tach moves while your trying to start it as that also runs off the trailing ignitor.

 

It is an '85 12A - good points, thanks, I'll have to check it out this weekend as I cant recall if the tach was bumping or not...
