    93 cavalier ecm same as 93 gp ecm?

    i think i have a bad puter. when i try to run codes i can't get a check engine light. anyhow, someone gave me a good ecm out of a 93 cavalier z24. all i need ot know is if the electronics are the same as a gp ecm.

    Carquest lists 2 separate ECMs for the 2 cars.

    My guess would be no.

    Make sure:
    Your SES bulb isn't burnt out
    You ECM fuse in the glovebox isn't blown
    ANy under hood ECM fuses aren't blown.

    ses bulb is good, and i've tried several others.
    all fuses and fusible links have been checked and rechecked.

    it's getting to the point where i'm going to pull the cutlass interior back out and send it off to the junk yard [br]Posted on: April 30, 2006, 07:33:41 PM_________________________________________________oh and i figure the part numbers will be different. but i'm thinking the electronics still might be the same.

    the ecm itself is only maybe 2/3 the size of my gp pcm. but, i know there is a beretta or cavalier pcm that is smaller than ours are and it has the same elctronics. i'm just not sure which years and such
