  1. Check fuse 30 30amp for me, is it blown?

Fuses are good
Customer: replied 8 months ago.
It was running fine then I went to start it and nothing. All the fuses seem to be good and ran power from the battery to the pump it comes on. Just no power to the fuel pump and the "wait to start light" doesn't even come on.

Power is good

Could the fuel bowl have caused this to happen if it's no good?
Expert:  Chris (aka- Moose) replied 8 months ago.

The fuel bowl will not effect the fuel pump.

Use the link below to finish up the testing for no fuel pump operation.

I'm trying to help my husband but he became confused
Expert:  Chris (aka- Moose) replied 8 months ago.

Does he know where the fuel pump relay is in the instrument panel relay box behind the dash.

Customer: replied 8 months ago.
No he doesn't
Expert:  Chris (aka- Moose) replied 8 months ago.

The relay block is above the drivers right shin and to the right. Turn on the hazard lights and follow the clicking. The turn signal relay is in the same block. We need to remove the pump relay and confirm there are 2 power pins there with the key on.
