It is very possible to get a bad fuel pump , especially some of the cheaper aftermarket
stuff. The only fuel filters are the one you changed and the sock on the pump.
Here are a some things to check .
First the fuel pump relay. Swap it with a similar relay and see if the problem goes
If you have access to a fuel pressure guage , connect that and see if you are in
fact loosing fuel pressure.
If you are loosing fuel pressure , (pump stops working ) try the following, this
should determine if the new pump is bad.
1. Locate the fuel pump driver module to the right of the rear seat cushion (pull the cushion to access it) and monitor voltage across the White/Red and Black/Pink wires to the fuel pump from the fuel pump driver module. If there is more than 7 volts across these wires while cranking, and the wires are OK from there to the pump, replace the pump. Also, if there is battery voltage out of the driver module on the White/Red wire, and the Black/Pink wire is jumped to ground, the fuel pressure should be over 60 PSI. If less, that confirms a bad fuel pump.
2. If battery voltage is present on the White/Red wire, but the driver module does not ground the Black/Pink wire while cranking, check Ground G302, which is the Black wire to the driver module, and grounds on the right (passenger) side of the trunk, behind the wheel well.
Note: If you get as far as dropping the tank again , take a close look at the plug to
the fuel pump. Make sure the connections are good and no signs of heat at the
