2007 Crank no start

[klackmeal]

About two years ago I reached out for auto trans info. The replies were very helpful and made for a successful fix/rebuild.

Once again I reach out. This time for a simple crank with no start situation. I believe the no start is due to a fuel issue; no fuel pressure. The schrader valve on the fuel rail shows zero fuel pressure. There is no buzzing sound from the fuel pump when the ignition is turned on. I am thinking the problem is the fuel pump, relay, or wiring.

A look online shows that this is not an isolated problem. Fixing it remains elusive. My truck is a 2007 Ram 1500, 5.7, automatic. It is probably classified as a “work truck”. Per “Vertical Visions” my vehicle does not have the fuse block that has a bypass fix. What would be really helpful would be a fuel pump wiring diagram. Also, helpful: Is there way for unplugging the wire connector on top of the fuel tank without dropping the tank?

Thanks for reading. All help is appreciated. I am including a image of the fuse box.

Have you checked the fuel pump relay?

I would be thrilled to be wrong on this: the relay cannot be replaced. It is built into the fuse block, TIPM, and considered a non-repairable item. Good news to report. There is 12 volts at the fuel pump electrical connection. So, the TIPM is probably good. Picked up a new pump this afternoon. Will be installing it tomorrow.

Cut a hole in the bed right above the tank opening. Just did this to my 02 as I don't have the right jack to safely lower mine
