i changed the icp a week ago to an aftermarket one, after a single drive it started leaking switched it back and did an oil change. Now it will not crank i used T6 5w40. i believe my ficm is bad and icp pigtail. any help would be greatly appreciated
tried replacing my icp sensor yesterday and i could not for the life of me get the fcim bolts loose to go from the top. I tried to do it without removal got the icp unplugged but couldn’t get it out. This morning i went from the bottom and not a single one of my sockets fit on the heat shield that right behind the icp sensor.
also the truck is now a crank no start.
any advice would be extremely helpful.
