I can't FICM believe it...

Quick background, bought a 06 F-250 6.0 lifted beautiful truck that I "had to have", ran fine for a week then wouldn't start in the mornings, well eventually it would after cranking for like 5-10min straight, yes I did kill the starter so there was the first $140...so I started researching my new vehicle and learn about the FICM and its shortcomings. Voltage on it just key on was 48.5V so I figured it was okay so I tried other non-start things like "stiction" etc... I removed the FICM opened it up and looked at the potential problem areas and didn't see anything that looked bad so put it back together installed it and still crap starting. Soooo yesterday I get it started and probe its voltage while running, 18-28V (oh my I think I see the smoking gun) so I remove it open it up and this time decide to remove the opoxy that covers some of the resistors that aren't soldered well and sure enough one falls right off! At this point I'm like a little school girl with excitement that I fricken actually found what was wrong, resoldered the 4 resistors reassembled all and this morning fired right up woooooo-hoooooo!!! Thank you to all that have beaten the FICM issue to death you are a God-send (I'm no mechanic at all but telling my wife I can fix it and her seriously doubting it just made it all the more sweet)

Thanks Again,

A bad ficm can be a very spendy thing if left operating. And if your voltage is that bad ya its not a good thing.
My suggestion is give ED at ficmrepair.com a call. He is not exspensive at all. And is very fast. If your not in high altitude or towing massive weight Id say look at something like the Atlas 40 tune. It will wake your truck up and you will even see a small boost in MPG's.
