install ficm,motor now toast

[kellyf]

Has anyone ever heard of a truck being overfueled after a ficm replacement?One of the guys I work with installed ficm.Test drove no problem.Pulle up in lane and started running poorly.Went on further test drive and truck ran hot and quit.Now no compression on 7 and 8 and knocks like crazy.

Was the FICM relay removed during the reprogram process?

I don't know if it Was Brad,but at first we thought we had a bad ficm because it would not start after repair was done and had a series of high side codes to injectors.The tech installed another ficm and it will now start and codes are gone,but engine sounds like marbles in a garbage can.The hotline states that a ficm could not cause this to occur,but I wonder.

I was had a 6.4 melt ever other cyclinder in the fireing order. hotline told me in could nt be casued by overfuel and a faulty pcm...

You said it ran hot, how does the oil filter stand pipe look. I had one that ran hot once and melted the injector o-rings and it overfueled. The oil filter stand pipe melted.
