Problem!!!!!

When I turn my car off something is still continuously running that it drains my car battery. I can't figure out what it might be but it never turns off. I have to disconnect the battery for it to turn off. Does anybody know what this might be? Any help would be appreciated. Thanks

Is this a new car?

Because it sounds like the fuel pump may have a kill switch that you are unaware of.

Trace the fuel pump wiring. There maybe a switch to turn it off.

If you open the fuel door and listen is it louder?

Are you carburated? If so you may have an external pump. In that case the pump would be mounted somewhere by the tank outside of it, probably by the fuel filter.

A common place for the switch would be by the drivers seat. Because that's where the original fuel pump relay was.

It's fuel injected. When I put the battery Leeds on I feel the fuel lines and I can feel the fuel moving. I don't know much about this and I am getting frustrated

You have to replace it if that's the problem.

It's under the drivers seat.

It's real easy. There are a couple wire harnesses and on bolt holding it in. If you have a Haynes or Chilton manual with a wiring diagram you can test it. If not you can Google one. I don't remember the proper way ,But you can test for voltage on the out end of the relay. it probably shouldn't have voltage when the key is off. But you will need to look at a diagram to find out what wire has voltage and what doesn't.

If this is over your head then just replace it. But really its pretty easy to test and or replace.

You are the man! I unplugged the relay and plugged it back in and the noise went away. A simple task and you knew what it was. Thank you for all your help

You're welcome Jeff, glad you found the problem.


dreamstang this one is yours, your mention of the relay first, triggered the connection in my brain for my answer.

I had the same problem and cheated and put a toggle switch for the fuel pump.
