Good afternoon,

You need to verify power is going to the pump itself.

I attached the circuit for the fuel pump. The relay is under the hood and you need to verify voltage to the relay. You will need a test light or a voltmeter.

Can you hear the pump run with the key on?

The pressure is 55 pounds.
