What your hearing may be the initial prime? When you first turn the key on, no crank, the pump will run for a few seconds, then stop if no rpm signal. Use a gage and check fuel pressure, check for injector pulse.

If your code reader won't work, check pin 16 at the datalink connector for voltage.

Yeah normally the prime lasts about 3 seconds. The pump never stops running though. And I get a reading of 64 psi at the fuel rail

Pin 16 also shows voltage

I can't tell what's going on? Have you tried a different code reader?

Maybe the fuel pump relay is hung-up or a faulty computer. Can you check for injector pulse?

Can you check voltage and ground at the fuel injector?
