Did you check for any applicable trouble codes? Did you check for voltage and ground at the pump connector for the motor? The dark green wire with white tracer is voltage for the pump motor, check with engine cranking. Black wire is ground. Also, do you have spark at the plugs? Injector pulse?

We checked the voltage. There is no power going to it. The oil pressure switch appears to be fine as well. Its not getting any fuel into the injectors.

The voltage for the pump motor comes from the fuel pump relay in the power distribution center, under the hood. The computer may not be grounding the relay for some reason, that is why I asked you to check for applicable trouble codes. That is also why I asked you to visually check for spark at the plugs and injector pulse, engine cranking.

You can check for applicable mil codes, yourself. You cycle the key, no crank. Cycle the key on--off, on--off, on, then the mil starts flashing, you count the flashes to get the codes. Your looking for two digit codes.

At the pump relay diagram, terminal 55 is hot all the time. Terminal 56 is voltage for the coil side of relay, goes hot with the key in the crank position. Terminal 53 is ground for the coil side of relay, controlled by the pcm. When the relay is energized that line with the arrowhead switches to terminal 52, that terminal carries voltage to the fuel pump.
