Default Did I smoke the PCM?

Sunday I was messing with the settings on my wife's '02 Z, (It uses a predator) and after making some changes, I stopped to upload the modified program. During the upload process the tuner displayed an incomplete/error message. I attempted to reload once again, with the same results. I then tried to restore it to the stock settings, and the programmer will not read from the ALDL. There is power to the connector, but it will not communicate. I even tried my handheld scanner and no dice, acts as if it's not connected. Remember, it will power up the handhelds, but not communicate. Any suggestions/ideas? The car will not start, fuel pump is not running, etc. There are no blown fuses, so I feel painfully certain the PCM said

I ordered HP Tuners Pro yesterday, but I'd kinda like some suggestions to hopefully get it running again before, as it may be a couple weeks before the HP Tuners arrives.

Try disconnecting the battery for a few minutes, then try again.

It sounds like it died. The few I have had do that at the shop just doing an oem re-flash required a new pcm to correct it. good luck

Sounds like its done ive been there twice since i started tuning my own car ala LS1Edit and you have all the same symtoms. I wouldnt remove power from it until you try one last time with HPT. If that doesnt work then remove power and try again. Unfortunately it sounds like you will be purchasing a new PCM

I was afraid this would be the consensus.

If you have to get the new PCM, return HP Tuners, and get EFILive because there is a new real time editing system which comes with a PCM, and you can use that in your car perminently. That way you get the most bang for your buck...new and best tuning software, and realtime editing!!

Best of Luck!!
