    Make sure Ficm Harness connectors are all snap locked in firmly and ground wire attached to manifold stud. Sounds like the main FICM harness isn't totally connected.

    It is got to looking some on the pins was backed down in there a little bit I'm thinking the ficm had an intermediate problem from connection. Wire get hot looses voltage.

    Now my only thing I couldn't find do a 7 pin ficm computer be swapped to a 4 pin ficm.

    I know the boards are not but what about the whole system

    All of the replacement FICM's are 4 pin. But if you've replaced yours, the PCM needs to be flashed to sync with the FICM.

    OK good deal.
    Ipr duty cycle is just about twice as high as what it should be at operating temp idle, but I think we need focus on why the PCM popped a 0603 while it was running.
