No. It has had a new key and cylinder installed 2 years ago though. I'll get you guys the VIN later. I need to read codes on the BCM body control module. What do I need to buy to do that? All I have is a codebuddy.

Hi, I drove home one night from work and parked the truck. A chevy Duramax 2500HD 6.5 L. The next day, it cut out after running for 2 seconds. I had a bunch of off-duty mechanic types look at it. They plugged in the code reader. There was one code, for an open circuit glowplug on cylinder #5. We keep starting it. It dies after exactly 2 seconds. Always. Here is some information: The passlock security tattletale comes on, but goes off or might stay on randomly after the engine quits. Not to jump to conclusions, but it may be a passlock issue. I have tried the 10 minute relearn procedure 4 times tonight. The security/passlock tattletale will either go off or stay solidly lit the whole time. It doesn't go out after 10 minutes like it's supposed to. The code buddy live data shows the FRP hits about 50000 kpa when the engine quits. That should be lots of fuel pressure, right? I've got the charger on the batteries. It reads a nice 14.5 volts for VPWR on the live data. What else would cause the engine to cut out so consistently at time = 2 seconds? I need some ideas. Thank you! More info: Maroon color 4x4 Allison 6 SPD Will add more as I have to. UPDATE::: I have bought a tech2. I have confirmed by reading the engine control module that the Vehicle Theft Deterrent Fuel Disable is activating, thereby killing the engine. The problem I have is that when I go to the Body Control Module and look at the security data, the passlock states, and other values are reading normally. I'm not sure the passlock is the problem. However I get U1000 U1301 Lost communication with xxxx in most of the modules. For instance the instrument panel cluster, the heating system, body control module and so on. When communications are compromised individual modules use default values as a failsafe. So the truck might shut off.
