2004 6.0 Excursion Slow Starting
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.
P.S. I also posted this in the 6.0 Diesel area of the forum.

It indicares one of two things if not both:
1. You need new batteries, not just one, two...
2. Your FICM (silver box on driverside valve cover) is going out
Replace the batteries with some good, strong batteries and retest...if it still cranks slow, check the voltage on your FICM.

47-48 volts indicate a good FICM, less and you may have a developing problem...test procedure below.
