Dual tank model?

I would suspect a faulty fuel pump wiring harness grounding out, or maybe a bad switch, bad relay or fuse.

1ST OF ALL, I always pray cause this needs all the help you can get:>) Then check the fuel filter, the fuel pressure regulator and then think about changing the pump. Thats a pain. You better change the fuel gage sending unit while your in there to fix your gage problems. Hope this helps you or someone else1.
