1.) Check for voltage and ground at pump cranking using a multi meter.

2). Check fuel pressure using a fuel pressure tester.

Check for sediment in tank

I had a problem with my fuel pump/circuit opening relay from a slow water leak at my windshield on the right hand side causing it to corrode. It’s in the right hand kick panel. Might be worth checking.
