FICM
Quick question the truck is starting fine... I have a scanguage that is hooked up reading the voltage on the FICM. When I start the truck the voltage runs about 42 volts until the glowplugs turn off and the alternator kicks in. It then runs on up to 48v and stays pretty consistent. Does this sound right or does the FICM need to be worked on... Just curious your thoughts as I try to make this truck as reliable as possible...,
Thanks
Daniel

Check the battery voltage at startup until the glow plugs turn off and the alternator turns on. If it is low enough it might be bringing down the FICM. Also check the battery and ground connections.
It is most likely the FICM, though.

In is fine once it is warmed up and I start her up.
Maybe I need to start saving for a Swamps 58v unit.

Andy, I had a couple friends do the 58V units, neither lasted long. The heat built by those 'upgraded' units was crazy! Not sure if the heat was the mitigating factor in the failure, but I am sure it didn't help.

We don't suggest the higher voltage modifications for precisely the reasons stated here.
The easiest and certainly most reliable path to better cold starting is migrating to 5W40 synthetic oil. The difference is night and day, especially in those cases where stiction has already begun to set in.
Thanks for all the positive comments about our service, guys. It is much appreciated.
