Mechanic says the fuel sender is bad on my pump but if that was the case would the low fuel light still get triggered when the fuel gets that low? I was thinking the sender was still good just needs a new motor for the fuel gauge or cluster replacement. Thoughts?

 

Fuel sender could be bad and still move around.

 

I do know the previous owner had the same problem. He got a used fuel pump from a junk yard, installed it and did the same thing. First of all I don't know why he would get one from a wreck, maybe to keep costs down. I removed the cluster a few weeks ago to replace the passenger airbag and while it was out I manually moved the needle to 3/4 of a tank. When I shut the car off all the gauges go back to the far left except that one. It almost seems dead. I just bought another cluster and have to pull the dash back apart to replace the top dash pad so I will try a different cluster then.
