Truck has been running terrific. This AM go out and no start. Batteries are fine, turn key on - ac blowers on, radio on, turn key to start - nothing. All power goes off until I return key from start position then the radio and power back . I checked all fuses, etc. There is a small relay or something under the fuse box and mounted to fender well with 13mm bolt that clicks when the key is turned to start. Just figures - always on Sunday.
And it is 114 outside and of course I left my truck out last night, so no shade.
Any guesses? Bad ignition switch maybe? No codes, I checked that first.

Problem solved. A friend from the dealer called me back, yes on Sunday and his day off. Simple fix - and I feel like a fool - turn on the alarm (factory)- disarm -
get in and start car.

 

I would REALLY like to hear the explanation on that one... What did you do to "arm" and then "disarm" the alarm? It would be my assumption that you most likely have the SKREEM system that has a chip in the key. Every time you put the key in the ignition the module picks up the rolling code from the key and allows the truck to start. If it does it again I would be looking at updating the TIPM as there is an issue with some that have a prob with a "won't crank" condition.

 

....have him check out tsb 08-021-06

 

I will check that out. I do have the chipped key. All I did to fix it was get out of the car and push lock on the key, then unlock on the key, got in and it started right up.
What I apparently did this morning was go out to the truck, hit unlock on the key - got in the car, and then inadvertently hit the lock button before or while putting the key in the ignition switch. This prevented the truck from cranking.
I would have thought that would have set off the horn a tootin. I do have the 18 05 06 flash. I will get this straightened out this week.

 

08-021-06 ? Can not find any reference to that TSB. Where can I find it?

 

I still dont know what caused the no crank issue. The truck will start now even if I get in the truck and hit the lock button on the key and then put it in the ignition and start. So that is not what caused the no power to starter. The dealer had no idea what went wrong only to say "we have fixed the occasional no crank by setting the alarm and then turning it off"
Voodoo electronics!
Got the abs recall done while there - took 30 minutes. The dealer did not know of the previously posted 08-021-06 tsb.

 

I read on another forum something about a yellow wire on the 06' near the starter. It supplies the trigger power for the starter. Apparently, the wire is easily chaffed and would cause the problem you've reported. I haven't checked mine to see if it's a problem.

 

Here is short details of TSB 08-021-06

My wifes Honda has a chip key and if you put in in and turn to start quick it kicks the theft system and shuts it down for 15 min. It only takes a 1 second time or about there if you turn the key slow it is ok. I have never had the problem because I have always had the wait to start thing of a CTD.

Artie - Thanks, Where did you get that info, do you have a link?

 

The TSB was on my DRBIII update DVD that just came in but I don't have any easy way of putting up.
