6.0 Hard start/Cold start issues
Hello all,
I have a 2007 6.0 that has issues with starting when it is cold (i mean no start in 12+ hours so it returns to exterior temp) and at about 60 degrees it starts to have some issues. it was 64 the other day and it took 3 key cycles for the glowplugs and 3 tries of 5 second cranks before it loped violently into life for about 10 seconds and started idling normally, it had minimal smoke though. i cleaned the MAF sensor and airfilter this weekend because the injectors were down 4% on fuel or something according to the diagnostics. help?
here is a video of it starting today, it started easier then it did yestarday for no reason... fresh diesel in the tank:
Thanks!

Have you gone through this issue with the FICM voltages?

i was having extremely rough cold starts at around 50 degrees and added rev x into the oil about a week ago, the next day it was 25 degrees when i started it and it started up like i had it plugged in all night, honestly is amazing to me how much better my 6.0 runs and starts after adding rev x. i am 100% impressed with rev x
