6.0 cold stat issue

[horseman23]

I am stumped, I have a 2003 6.0 that has issues on the first cold start of the day. engine will sputter and sometimes quit. even when it quits it aways fires right up on the second try. The only code is for the glow plug mod......but it is in the upper 80s and low 90s here. When id does start on that first cold start there is usually a puff of grey smoke. I was told to look at the ICP, but again, no code. Any ideas??

forgot to mention, new injectors less than a year ago.

You need a monitor, google ficm check procedures, need codes pulled.

I had a buddy hook it to his scanner and run diagnostics, everything checked out with the exception the glow plug mod. could that be the issue this time of year? also, seems to be a small oil leak in the back of the turbo at the oil inlet tube, could presure be bleeding off over night? Today I turned key on and after the wait to start light whent off turnd the key back off, repeted and it fired right up on the second cycle, I did not try to start at the first cycle

Ok, did this start after you did something?
Did you use motorcraft filters?
What type oil did you use?
Bad glow plugs should not be the problem right now.
I think it would be wise to check fuel pressure right now.
The oil inlet for the turbo is near the top, is that what you mean, what do you mean by small leak?
I'm not sure if that could be your problem, but I would get it taken care of soon.

No, truck is new to me and this just sarted.
It is due an oil change and does not have motorcraft filter or cap

Ok, better start there, very important.
Fuel filters also.
You need to get a monitor on that truck, essential on the 6.0.

will do. Thanks for the help and info!

Most guys suggest rotella t6 synthetic or similar to try to prevent injector stiction.

you sure the oil leak isn't from your icp sensor? the icp sensor on a 2003 is right behind the turbo, and can mess up readings. i'd like to know what your ficm mpwr voltage is while cranking and what your icp pressure is while cranking. not every fault sets a code
