75, 2.0, djet. Won't fire. Spark is good. A little starting fluid in the intake and it fires. Clearly a fuel problem. I'm not hearing the fuel pump. Shouldn't I hear it for a few seconds when first turning ignition on? I checked the fuse (#25 on the relay board) and it's good. I'll put a multimeter on the pump terminals to check for power next, but thought I'd throw this out there to the collective for any other input until I can get back to it. Grounds are also on the list. Or put power directly to the pump and see if it runs.

Hey Al, it looks like we are in this together. Spoke was super helpful, and of course the Bowlsby PDF from your thread.
I thought if I put power directly to the pump, it should turn. Nope. So it makes me think the pump is bad. But I'm still open to the input from the experts. Funny the Dr mentioned the fuse when we both proved that straight away. |

My recent experience, Had the car running, then stripped for a full resto. Figured it ran before, re installed the 3 port pump, and the relatively complex plumbing at the front under the tank. Luckily didnt install the tank (tank is a coffee can). Direct wired the pump to a battery (eliminating EVERYTHING). Nothing. Took pump apart (again), cleaned it (again), got pump to run. Looking at the return back to the coffee can, barely any fuel. Replaced it with an Airtex, replumbed the lines, and bingo. Running again.
Point is, wiring the pump directly to a battery was extremely helpful, isolating all other potential issues. |
