    Cool Bad 0411 PCM?

    Hello all! I’ve been beating my head against the wall with my ‘96 Trans Am
    LT1 0411 PCM swap.
    a year ago, February, after successfully doing the swap, I was returning home from
    work one night, and the car backfired and died. The culprit was a bad Ignition module.
    since the car was down, I installed a brand new 383 stroker, LT4 hot cam, ported heads,
    long tube headers,etc. I have tested each and every sensor, checked my pinouts again and again
    but I cannot get this turd to fire the ignition coil, the module and coil are good, even the
    crankshaft sensor tested good. I have used the LS Droid program to flash and re flash the three
    0411 PCM’s I have, using the last good tune I was running before it died.

    I guess the Question I am asking here, is even if you can read the PCM, write the calibrations,
    Can the PCM be bad? I’m at my wits end here, If I don’t solve this turds problem soon,
    one of two things is gonna happen:
    one: End up divorced, in a mental hospital
    or two:
    I have a “ Fire sale”🤣(did I say that?)

    let me know what you guy’s think could be my gremlin.
    thanks!
