Ok my 2008 started this issue a couple months ago, put the key in go to start nothing, wont turn over, checked power to the starter all good, unhook the batteries, hook them back up it fires right up, crusing down the road, the security light comes on, doesnt run any different, then it will go out, go to shut the truck off, pull the key out and it fires back up :confused: the only thing else i can think of is ignition switch? Im at a lose as far as what else to check maybe you guys know of something i forgot to check or didnt know to check

wait... so it starts up when you pull the key out? WTF? Or did I read it wrong? The key has a rfid chip in it, the truck shouldn't even be able to start without the key in the ignition.

yeah you read it correctly, turn it in the off position and pull the key out the truck will start up, put the key back in and it shuts off, ya im not sure WTF is going on, my next step is to dig into the steering colum to figure out wtf is going on

Sounds like a BCM issue to me maybe. I bet the stealer could reflash the BCM and it would probably fix it.

Twin turbo's usually kill a warranty... :)

I was going to say maybe something with the VATS, but that usually kills the truck rather than brings it to life on it's own.

Also look for a fuse that might be blown but does not completely open the circuit......I've seen issues like that compromise anti theft systems.

there was a recall a while ago for the security system not allowing the truck to start.
But never heard of anything like your describing.....

Well got an update from the dealer, they just wanted to call and inform me my egr cooler and dpf were missing, but cant figure out why it doesnt throw any codes, apparently mine vehicle is the first one they've seen with both of those removed, but they are still working on the no crank no start issue :rof :rof
