Duramax Stays Running Key Off at Naomi Carl blog

Duramax Stays Running Key Off. The only way i can stop the engine is pull the solenoid wire or unground the pmd (which probably isn't good for it). Jump to latest follow 2k. I would have to wiggle the key when shutting the truck off to get it to ignition to realize the key is being pulled out and shut down. It must be some kind of safety mod since shutting the engine off in drive would cause a hard brake pedal or brake failure. When i turn the ignition off and pull out the key everything on the dash turns off but the engine stays running. I put the key back in and turned it to the run pisition the off and it shut down. My truck has done this in the past. The dash power off, the a/c, the radio all shut off but the engine kept running. I remove relay#49 (pwr/trn) from under hood fuse/relay block & engine shuts off. I let it run with the key off for 30 min hoping the fuel pump.
