My 6.0 hates it cold!!

[gillaxxl]

I have a 2003 excursion and it just doesn't want to start when its cold.(below 60 degrees) i have had it for three years and never had to plug it in before. i had the edge system first then traded that for the SCT.(alot nicer) I have an idea that it is a glow plug problem but what? I am guessing that if a couple of glow plugs were working it would still fire but i killed the batteries trying to start it the other day. GPCM?? any ifo would be greatly appreciated.

first thing a techs gonna do is flash it with the newest flash. the inductive heating one. sounds like you may have some bad injectors though, that is what I would suspect if my truck was doing that. good luck to you and welcome.

what would be the fix? cleaning the injectors or new ones?

60 degrees sound awful warm to not start because of glow plugs. I would suspect injector stiction. If you are still under 100k miles, take it to the dealer and let them take care of it. Even if your warranty is done, it would be worth the money to have them give you the inductive heating strategy. It helps with stiction.

there is a second generation of this cold fix flash and i have been told that these injectors can develope this cold start issue at any time - which makes it seem like a GP failure - and 99% of the time this flash will fix it. It helped mine alot at 75k miles.

Thanks for the info guys. I am gonna take a few minutes to check the amps to the glow plugs just to be sure then its off to the dealer.
