There is a relay and fuses located on the engine harness by the ecm and in the battery box, There is also only 2 pins to check on the lift pump harness The pump will only run for a short time at key on. This is the only time you will see voltage.
Remove the fuel lift pump power connector at the fuel lift pump.
Insert a test lead into the fuel lift pump supply pin and another test lead into the fuel lift pump return pin on the harness connector. Turn the keyswitch on and measure the voltage with a multimeter.
The voltage must be battery voltage. If voltage is not present, check the fuse on the fuel lift pump relay supply line. Replace if necessary.
The lift pump ONLY RUNS AT KEY ON FOR A SHORT PERIOD. That is the only time you will hear it. Also try to activate it by bumping over the engine but not starting. It would come on that way too.
