The fuel pump seems to have gone out again. Last year we replaced it with one from Auto Zone. Well it seems this pump did not do the job required. So today I put five Gallons of fuel in the tank because after the new pump was put in it would act like it's out of gas when it still had 1/4 a tank of fuel in it.

Again like last time I'm not getting any pressure under the hood I don't hear the fuel pump coming on when the key is in the "on" position.

Hi, If no fuel pump action, check voltage and ground at the fuel pump connector, engine cranking. Gray wire is voltage, black wire is ground. Any trouble codes?

I would not know at this time. I have not had the chance to work on it. All I know is Auto Zone sells poor parts.
