Well I put in the computer and it runs, but the sentry key immobilizer system shuts it down after 3 seconds. So based on what Alldada is telling me, I will either need to take it to the dealer when it gets the front axle underneath it to have them program the new PCM with their DRB III tool or buy a scanner that supports the "vin number write" function to manually enter the vin into the PCM. I think I'm going to end up down at the dealership and having them do it because even our $600 autoxray scanner tool doesn't have the vin write function.
course, I could probably solve the whole thing by just cutting out the immobilizer unit attached to the ignition switch, but I'd rather not cobble job it. and I'm worried that if I do something like that I'll have an amber immobilizer light or check engine light thats always on, and then it won't be able to pass inspection so the state of Wisconsin will liscense it.
not real important, but I thought I'd let everybody know what was going on and so that maybe some poor bastard with the same problem can find this thread on google and get a better clue about what to do.
