I have a 2004 Excursion Limited with the 6.0 diesel and about 95,000 miles. I am the second owner and bought it with 35,000 miles on it.
It has been a great truck and I have had practically no problems with it. It threw a code at about 80,000 miles that turned out to be the ICP sensor. I replaced it and haven't had any other issues.
Recently I have noticed that it takes more cranking to get started. Not too bad, but still different. It used to just pop right off and now it sometimes takes a couple of cycles through the glow plug timer and a couple of reasonably short cranking periods to get it to fire.
What can I do to improve this? Does it indicate a problem? The beginning of what will become a problem? Any advice? Thanks in advance.
batteries maybe getting low. i had to get new batteries about 2 yr ago, and truck cranks fine in cold weather.(GA cold weather that is)
but every 6.0 i have seen cranks slow. at work i drive a 3500 dodge cummins. and will say they those things crank right up with the 200k miles i got on work truck. when u jump in my f350 after work, seems like it will never crank sometimes.
