I have already addressed this in my posts and also with a link in them to VATS info where it is discussed. You seem to ask for help, but not heed any help given. Have you scanned it to see if there is a DTC for loss of the fuel enable signal?

Just because it cranks does not mean the switch is in perfect adjustment. There are several positions the switch contacts have to be in for it to operate properly. RUN, START, OFF etc. If it is not making proper contact in the RUN position, some things might not get power. Not saying that this is your trouble, but just saying it is ok does not prove it is. Check the fuses for all things that should have power with the key ON and see if they do. You have to start narrowing things down with some real testing.

The BCM provides the chime for various warnings. The fact that it chimes with the key off indicates A) it is powered with the key off, indicating a short in the wiring or a problem with the ignition switch when it is in the "off" or "lock" position; B) something that triggers the chime is active, like the key in the ignition with the door open, etc., or there is a short in the wiring at the BCM.
Just curious.... why do you reach under the dash and touch the BCM when you get in the car?
