Fuel pump

[vagabundo]

I am the original owner of a 1973 2.0 with stock EFI and about 115K miles. Several years ago I had a shop relocate the fuel pump up front while I had the tank out. The car hasn't been driven much since then but I got back on the road recently and the car was driving great after I sorted out some relay problems.

Last week I had to jump start the car knowing the battery was shot. Car was runnin', so I took it out but could not restart to get it back home, even with a jump. My local mechanic replaced the battery and was able to get the car started but it appears the fuel pump is shot (he tapped it with a l'il hammer to get it going).

Here's my problem -- I know these 2.0 pumps are NLA but I could take out the pump and send it Auto ATL for a rebuild. I saw on another thread that the ground wire could be a culprit, so I'm going to check that first. Are there any other things I should be looking at before I take out the pump? I would hate to miss a shade-tree fix before I go down that road.

Thanks in advance for any helpful advice.

If a tap on the pump gets it to work, it's the electric motor in the pump that is going bad.

If you have a decent auto electric place locally (they will mostly rebuild alternators and probably starters) they should be able to rebuild the pump.

Dave -- thank you for your post. Rather than rebuilding the part, I'm inclined to use a NOS '74-'75 pump or a Carter if I can figure out how to get the recirc line back into the tank from the pressure regulator and fit a fuel filter in (assuming I understand how the pump is plumbed now ) thanks again -- vb

Fuel comes from the supply fitting on the tank, through the filter, to the pump. From the pump, to the right-side fuel rail, to the left-side fuel rail, and then to the fuel pressure regulator. From the regulator, it goes back through the center tunnel to the return fitting on the tank.

The 70-74 cars have a "Y" in the line from the regulator to the tank; the third branch of the Y goes to the return fitting on the fuel pump.

Don't do a bandaid repair or workaround...Have the integrity to fix it correctly, with the original and correct part. You will be miles ahead.
