What does the security light do when you try to start it

it died as if the key was turned off, and the security light stays on

Search on the Internet for the passlock relearn process and try that

we already tried that, still nothing

Bad ignition switch? Try jumper the starter

I had a similar problem. I unhooked both batteries for 10 minutes then hooked them back up and I was in business.

Everybody is giving you a hard time because you "roll coal", we already have the EPA up our a$$, forcing DPF and ULSD upon us, be part of the solution, not the problem. :thumb:

You blew a mega fuse or a pin in the ecu harrness got unseated...

Should be on the passengers side fire wall if I remember correctly...

 

[05Duramax6.6]

i will look

ISn't hat Mega fuse (175 amp) under the fuse panel cover on the drivers side fender fuse box? like you have to lift off the lower fuse box cover to see if it is blown? Keep checking what we say and will have you and your mom Oraling the coal in no time!

 

[05Duramax6.6]

where exactly is the Mega Fuse located? ive looked all over and still cannot find it

 

[ty_LBZ]

IIRC, the only mega fuse supplies power to the intake air heater

I had a similar issue although it was on a kodiak dump truck. Ended up being the ecm connection. Really to figure these things out you can try the basics but generally you need a good understanding of automotive electrical circuits and good schematics. Problem like this can take minutes to many hours to diagnose. Good luck.

It could be so many things that you really need to take the truck to a shop and have them diagnose it in person.

I think your mom should be thrown in jail for rolling coal.:roflmao::angel:

 

[Awenta]

Or trace back everything. There is no one certain thing that causes this . Can be so many things as bac said.

Check both ground connections at your batteries and make sure they are tight.
