Hey I'm new here, I'm having a issue with my 03 f350 6.0. I recently had a ficm problem truck would start good cold once it warmed up it would die. I let it sit 10 mins it would fire back up. After talking with ed at ficm repair we found the logic board was bad. I replaced the ficm truck runs great doesn't shut down I thought problem was fixed. Now when I shut the truck off it won't start back up. Here's what I have found I am using a scan gauge it has ficm syn, irp is 15, ficm pwr is 48, icp says 750. when I turn the truck off and cycle the key back on icp says 3000 then it will drop to 0 after 15 secs truck will fire back up. One other thing is the injector pre cycle doesn't seem to be cycling when key is on. Any help would be appreciated.
