1991 Dodge Shadow Fuel pump power but not working

Thank you for such a fast response.

I actually switched the fuse with another 20 amp. And still nothing. I assume this shorted wire can be anywhere from the fuse box to the pump?

I guess I'm going wire fishing. Lol

Thanks again

No problem. I'm just glad for the assistance.

I did find one odd thing so far. There isn't any power to the fuel pump fuse with the key on or off. But I have a steady 12 volts to the pump connector as long as the key is on ( 12 volts since I charged the bat.) But the pump will not run without direct battery voltage. Can you explain how this could be?

I don't have much more hair to pull out.

BMRFIXIT;

Since the price was low, I just purchased the relay. After installing it, I still had no pump action. I held a test light at the fuse, turned the key to "On" and the test light lit with a relay click for 2-3 seconds. When I tried to crank, the test light lit as I cranked the engine. The car must have needed that relay also.

Still power to the pump connector with the key sitting in the "On" position. Oddly enough, if I pull the Fuel Pump fuse at that point, the voltage to the connector drops to "0". Would this mean that the problem is "before" the fuse block?

One other thing, to confirm that there was spark, we used starting fluid when I tried the cranking and the car ran until the starting fluid burned out. The person helping me said that he could hear the TBI clicking as I cranked. But of course, no fuel was being sent.

I thank you for all of your help. I will be making another donation when I get paid since you have spent so much time with this.

One thing that I thought was a problem was that the fuel pump connector has a steady 12 volts even if the car is just sitting in the "on" position without the car running. I thought that the power was cut by the relay after a few seconds if you don't crank the engine.

Should there be current to the fuel pump connector with the car not running but just in the ON position?

It is the dark green/Black

I'll check on that right away. You're the best

I did notice that if I pull the coil plug, the power in that wire at the pump connector drops to zero until I plug the coil back in. Is this also normal?

I really appreciate all the help. Obviously, it may take me a bit to complete this task. I will get back with you with what I find.

More food for your piggy bank is coming tomorrow :)

The problem was located and the fuel pump is working great now.

The problem was a ground wire had corroded at the bolt due to time and a leak in the windshield. It corroded to the point of no contact with the body of the car. There were three black wires that were soldiered to a small piece of metal inside the harness (I thought Ford was the only Mfgr. With crazy ideas). There was then another wire soldiered to this bare metal piece and going to a bolt on the drivers side at the bottom of the trim beside the emergency brake pedal. The harness Is supposed to be in a plastic runner going down the body from the drivers door to the firewall. This plastic had broken and (over time) allowed the harness to ride down to the floor panel where there was moisture from a leak in the windshield. And caused the harness to be stepped on for quite some time.

Well, we all know what time and moisture will do to exposed metal.

There was also a problem with the cooling fan not having power. Someone had run a jump wire to power under the hood. By fixing this ground, the cooling fan was also corrected.

Thank you so much for the help on this.
