In the relay slot, I jumped from always hot (L/S) to bottom slot and current made it to fuel pump.


In the relay slot, the R/S (relay control) gonna investigate if it lights up with K/O/E/Off.

I only had the pump run for 6 seconds or so before start. I try to wait for the fuel pump whirr to stop before I crank.if you can not your fuel pump you might get a start if the problem is in the fuel pump control circuit. Can you do a full scan now and I errors?

Dono how to run a full scan with the equipment I have.


I'd appreciate a recommendation for a "full scan" tool I can buy or rent.


Power is coming into fuse 51, not reaching the control point for the relay.


The ground is good at the pump.

If you get voltage to the fuel pump when you jump the relay contact, I would think that the fuel pump relay is the problem. When you bypass the relay, does the fuel pump run? If yes, try starting the engine.

Well folks, I've reached the limit of my ability to diagnose this problem.
Thanks for all the help.
I'll necro-update if I get this figured out.

I use the foxwell NT510. It's saved my bacon numerous times.

As Don also mentioned: if you can get fuel pump to run try to start the car. You can figure out after why the fuel pump circuit isnt working.

Well, problem solved but I still want a professional scan on the car.



All the comments made above helped; the one comment about hearing the pump whirl when jumped seemed to be key.



I had ordered a new pump on day one; it arrived and I thought "why not drop it in".


There was some bright metal shavings at the bottom of the tank, I used a telescopic magnet to fish them out.


Car runs fine; gonna road test tomorrow.


Many thanks everyone.

I think post number 34 was the key post to what was the problem.

If you're one of those drivers that run the gas to almost empty, STOP doing it. Gasoline is used to cool the electric motor and when you run the tank to almost empty you don't have enough gasoline to keep the motor cool. The motor will overheat and when the motor overheats, the solder on the commutator will start to melt and get flung out.

Nothing wrong with the fuel pump circuit. The circuit is only on for about 2 seconds when the key is turned to the run position. Unless you have a helper turning the key for you, by the time you turn the key on and go back to the fuel pump area, the circuit will have turn itself off if the engine isn't running. Set the test meter to beep or use a scope on the rope and observe if the scope light up when you turn the key to the run position.
