Truck won't shut off
 

This has happened to me twice now. Turn the truck off take the key out and it keeps on running. First time I thought my Edge module might have a turbo timer that I turned on without knowing it but 10min later still running. Had to pull the fuel relay to kill it. Second time, I decided to take it for a drive after turning the key off and on a couple times and I noticed when it shifted to 2nd boost was limited to 10psi, 3rd and 4th to 8psi and it acted like it was running out of fuel but I still had 14psi of fuel pressure. When I got back, still wouldn't shut off. After pulling the relay, I started it up and drove it and everything was normal. Any ideas on what caused this? Fuel shutoff solenoid? Thanks in advance.

remove your edge completely and see if this cures it. sounds like a programmer issue to me.

Do u have the edge juice w/attitude cts? If so u may have a turbo timer cause my truck just did that to me as well after I hooked up the constant wire in the engine bay fuse box. I turned the turbo timer off in the settings and my truck turned off.
