Re: pcm hitting the bucket?

so i guees swap it out and see if another pcm works cuz hes tuner wont read me nomore nothing and i was thinking it was fault but didnt want to hear him B+++h about it
 


all fuses were checked non blown so im lost because im build l36 bottom l67 top i blew my bottom end racing a genesis i won till she went and spun a bearing sad face lol but i have a xp cammed l36 im putting my 3.0 pulley headers my heads and ported m90 on and im goin need to tune it and i need to fix this pcm problem
 
If you can't communicate with two different devices and the car starts and runs, the problem isn't the pcm. Fix the fuse that FFDP mentioned because w/o power to the OBD2 port...you can't communicate.
 
I had a PCM go bad once where it wouldnt accept any kind of communication/writing to it (even outside of the car) but the car ran normally. Was weird. Replaced it and the new one worked fine.
