Truck wont start, no turning over, no nothing. I did notice the security light came back on????? When I say nothing I get nothing. The battery's are good.

 

Also, my key fobs (both of them) wont lock or unlock the truck?? and I can't get the truck to go in the on position before the start position???

 

I'd start by looking at the ground cables making sure the ends are clean and free of green fuzzy stuff.

 

My first guess. Check batteries.

If good, leave disconnected for 15 to 20 mins see if it resets.

 

His too... he already said that in his first post.

 

Any interior lights? Also what do you mean you can get the key to go in the on position before starting, \\

 

There's a fuse in the PDC under the hood that controls the security system, door locks, and power windows; That'd be my first check.

When you talk about the key, do you mean you get no gauge movement or warning lights when the key is in the "run" position?

 

Just an update to let you'all know,I did some searching on the web, here and elsewhere, and came up with "wireless control module". Apparently when its cold, sometimes inserting the key can cause an electrostatic charge and lock up the security system or the WCM. I unhooked both batteries for about three minutes and BINGO truck starts. There is a service bulletin out on this for 07 trucks. The odd thing to me when this was happening was neither key fob worked the door locks and I could not turn the key to the on position before turning it to the point where the gauges lit up????? Also I saw where you could remove fuse #11 and achieve the same thing as removing the battery cables. After getting it going I checked for codes and got nothing. Thanks everyone for your help, Sam
