Did you use a voltmeter connected to a good ground to check fuses as I recommended to BOTH fuse boxes?Thanks again everyone for your advice and help. I followed Autoprof's advice and check all fuses which seem to be functioning correctly.
The key will not release from the switch.
After I clear the P0601 code and check engine light, it comes back as soon as I switch to the on position. Any further help anyone can give would be greatly appreciated before I give the dealer all my money. Thanks in advance.

Is this new? you never mentioned it.
Did you also check grounds? Especially the body grounds for ECM as Dicktator showed and the ones on the battery cable?
