2006 Duramax problems

[Newlywv]

Hello
I have a 2006 Chevy Kodiak 5500, with 6.6 Duramax. It will start up and run fine for exactly 39 seconds then shuts down, then restarts immediately and will do same thing again.
We have replaced all injectors, glow plugs and injector pump, fuel filters. Still does the same thing, 39 seconds every time. Any advice is greatly appreciated.

thanks,
Rich

Try shutting of the security with efi live

Is that done with the tech 2? I'm not familiar with efi live

Is it low on coolant?

Is it low on coolant?

I knew I had this problem before and now I remember what it was..

Not low on coolant, even jumped across sensor and tried bypassing it.

Sounds like a security-related issue my 2002 did that when the transponder key stopped working

Had a Kodiac do that to me years ago on fresh startup. Ended up we had the coolant overflow hanging upside down before the front end went back together.. Flipped it over and the truck ran fine, had me scratching my head for two days.

You can disable your vats security system with efi live.
