Truck wont start

[dayusex]

So the truck wont start, it is "cold" (35F), and it just wont start. Plenty of fuel, alternator and batteries are a year old. Basically I let the glowplugs do their thing, then try to fire it up. It sounds asthmatic then nothing happens. Cycle the glowplugs multiple times same thing. When im cranking it, I even give it "gas" (had to do this the last week), and still nothing. Figure maybe its filters, so drain the HFCM, and swap both filters, still the EXACT same thing. This truck is driving me nuts, so im sitting home from work now because I cant get there AAAAAAAAAAAHHHHHHHHH. Help!

Has the cold weather reflash been done? Shouldnt need to be plugged in at 35 degrees

[dayusex]

nope not plugged in, last year when it was this cold, never had to plug in

[dayusex]

i dont know if the cold weather reflash has been done, I have the flash that has the injector "ticking" when you shut off the motor.

[Dave]

Thats an old flash. You need the new one

[dayusex]

so its not my HPOP, or fuel pump worries like I have been fearing?! Wont getting the new flash mean I need new tune files?

Follow the link about unlocking your box in the 6.0 tech files and you should not need new tunes.
