Changed fuel pump but still don't start, we put gas in the injector and it started but won't stay started, is there a fuel reset switch?

It MAY not, if you have power out of Fuel Pump relay and none at fuel pump, then I would suspect one.

. Test fuel pump fuse with a test light or multimeter. It's likely in the under hood fuse box. Clean contacts, if necessary.

. Check fuel pump relay, which is likely in the under hood fuse/relay box. Clean contacts, if necessary.

. Check ignition switch for wear, pitting, or melting.

. Check the ECM, which often controls power to the fuel pump relay. Be sure to clean the main ECM ground.
