05 silverado 1500 no start, fuel guage reads empty

[bossier62guy]

I really don't think the fuel pressure has anything to do w/ the starting circuit....at least not what I can find so far. I did however run across this a bit ago.

 

The instrument panel cluster (IPC) displays the fuel level as determined by the powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating the fuel level percent. The fuel gage defaults to empty if:

• The PCM detects a malfunction in the fuel level sensor circuit.

• The IPC detects a loss of class 2 communications with the PCM.

 

Here are the starting schematics...starting.pdf

 

BTW....when you turn the key to the run position....is the fuel gauge the only weird thing that's happening?

No updates?

Found the problem. The PCM 1 fuse was not making contact in the fuse holder.

That'll do it alright....glad you got it fixed.
