No check engine light and unknown about codes. What should the fuel pressure be? Is that with the key on or while cranking?

No sound from fuel pump cycling when the key is first turned on, all fuses are good both in cab and under good. Is there a way to verify power to the fuel pump.
Expert:  Roy replied 1 year ago.

you need to go to the fuel pump module and check the voltage at the connector.

FYI I checked the fuel pump relay and even shorted it, no pump noises from the fuel pump. Took the bed off the truck, installed a new pump and everything works. Thanks for your help.
