Couple of Questions

[Lastcaveman]

First: When doing the voltage test on the FICM fix can I just turn the key on and check the voltage. and then start the motor and check the voltage or do I actually have to have a second party inside the truck working the key? I know I wont get the cranking voltage but do I need it? Second question: I just found a crack in the top of my secondary fuel filter cap, leaking fuel while driving. Could that cause a fuel pressure leak enough to set off codes?

i had my dad do the key that way i could get cranking but i dont see why you cant turn the key and check it then start it and do the same.

dont know if the crack will cause codes, i think it should losing gas like that so it cant build the right pressure

It certainly is good to be leaking diesel fuel all over your engine. It will also be hard to maintain fuel pressure with the cap cracked. Caps are cheap. Go get one from you local International dealer. Much cheaper than the Ford cap for the same thing.

Thanks for your answers. I just bought a cap from the classifieds here. I`m hoping that is the answer. I`m getting P0611 after a 150 miles or so. I checked the voltages on the FICM and they seem right 48 key on motor off 46.5 motor running. Motor starts good. runs smooth but I now have a small increase in RPM`s as it set`s idling. I guess its a surge.
