Bad Bcm?
Bad Bcm? i have a 01 trans am. i came home from vacation and tried to start it but it wouldnt start. it cranks but nothin else. there is no spark or fuel. everything else seems to work fine, but the gages dont. and my friend tried to scan the computer but it said it was unable to communicate. he thinks its the body control module. he removed it and it was kinda hot. we didnt take the bcm apart yet, but does anyone know if this is right? or is there another problem we should check? we already checked all the fues and relays. and while i was on vacation it did rain a lot here. while no water actually got in the car it was very humid and i think moisture may have gotten in the car. any help would be appreciated.
The engine would start and run for a second then cut off if it was the BCM security. Sounds like an overall electrical problem or PCM issue. You should check out to see if the PCM has power on all of its power wires. Make sure all your fuses are good.
my car has 93000 miles. but i just called the shop and he said if it is the computer theyll prob just dyno tune it again. and he said the comp is about 250$ the dyno tune prob wont be 2 expensive . so if thats the case it still wont cost that much more than the fuel pump, which is what we thought it was at first. it kinda sounds like thats whats gonna happen. its not a huge deal i have another car i barely drive the ta anymore. but thanks for the help. and ill let u know what happens.

Verdad Gallardo my friends thats workin on my car just called me. he said he and the guys at his work think its something wrong w the ignition. he said he wants to take the steering wheel off cuz it might be the tumbler. i told him that doesnt sound right to me. what do u think? even if somethnig was wrong w the tumbler the comp would still work right?
You would know if it was a lock tumbler because it wouldn't rotate.
Bad ign switch? Not likely. You wouldn't see the gauges come on and it wouldn't turn over.
If you can hear the car chiming and everything else is coming on I would look to see if the PCM is getting power.
Can you hear the IAC motor moving when you turn on the car?

my buddy the mechanic just called me, he took a look at the computer and said it definitely looks like it was damaged from water. he said the outside is coroded. i live in chicago and a week and a half ago there was a lot of rain and my car was sitting outside, i couldnt move it cuz i was in california.i think its because i have an aftermarket ram air hood. it fit pretty good, but i bet thats what let so much water hit the comp. does taht make sense to u? so hes callin the dealer to get a price ill be able to get it at a discount, but ill have to take the car back to speed inc for a retune..
