Just had issue with car stalling and dieing. Took it
for a diagnostics test, said the full pump is bad.
Replaced it but now the pump won't kick on.
Battery is new plus a few other things. It had been
sittin 4 years before now. In need of help, at my
wit's end.

Fuses are located at the fuse block under the hood pass side. The fuel pump connector is on the driverside rear. There is a red wire wire under the hood on the passenger side. It has a female connector on it. That is a test wire for the fuel pump. Hook up 12V lead right from the battery and listen for the pump to come on. If the pump comes on then the issue is on the switch side of the circuit. Hope this will help.
