Did they ever figure your car out...hope I never have this problem but its nice to know for future ts..

rhyno

just reading thru, did the car die after you installed the nitrous feed?!? maybe disconnect that in its entirety and see how symptoms are.

Just an fyi my freinds 05 c6 has gone through 2 bad PCMs...i would swap the pcm and rule that out

615C6

No they haven't figured it out yet. The used PCM that I bought for them to try was from a 06 and it wasn't the right PCM. I thought 05-13 was the same. Apparently something with the 2005 PCM's weren't that great because GM redesigned the PCM for 06-13. The 2005 have a E40 PCM and 06-13 have a different which I believe is E38 if I remember correctly.I bought a new OEM PCM and gave it to the dealer today. I should find something out by tomorrow if the new PCM is the problem. All nitrous wiring is removed until they figure it out. At this point I believe the nitrous had nothing to do with it.

Was is acting the same as mine? Completely dead?

Just a update on the problem. The dealer tried the new PCM and got the car to power up and was able to retrieve 4 codes from the steering column. The bad news is they telling me they don't know which codes and the car no longer powers up. They think another module is pulling it down. Not sure if they giving me the run aroun are not but that's all I got for now.

With no forward progress in almost 3 months I decided to take the car back. It's currently at my home in my garage. I purchased a genuine tech 2 with the latest software and TIS2000. Won't be home for another 2 weeks but looking forward to bringing this lil beast back. Thanks everyone.

have they tried removing the starter and bench testing it?

615C6

Starter is good. I jumped the starter relay and the car turned over. The problem is the car won't power up. Almost like a dead battery.

Anything new... I am watching intently as I have the same issue in my 2007.

Mine did the exact same thing. Cranked, no start. It was a bad PCM. Luckily they aren't too expensive.

h2oskier9864

For the record mine doesn't crank. The car is completely dead then it will go into accessory mode and get all kinds of trouble messages on dash. I then hit start and it dies again. The inside lights do not work and the head lights do not come on either when it goes into accessory mode.

Z06_N_SD

When I said crank, I was referring to jumping the starter...cranks over but no start.
I pressed the start button, power would go dead for about 10 secs , then come back on.

Just got home from work and my tech 2 was here. Plugged the tech 2 into the DLC and I cant communicate with any module. Any suggestions? Let the fun begin!

Z06_N_SD

SAME exact problem I had. It's your ebcm or Pcm. Most likely PCM. They go for about $300 and the dealer will have to program it to your car.

615C6

I already tried a BCM and PCM. I also have a tech 2 so I wont need to go to the dealer for programing. Unless the pcm or bcm that I bought new are bad off the shelf. Didn't you mention that your gauges would light up? Mine is completely dead. Only thing that works is my power seats and headlights. Cluster,radio,key fob,doors,windows, etc are not working.

Z06_N_SD

Did the dealer reprogram your new pcm? Or did you just plug and play?

Z06_N_SD

And for me, it was:
Push start, cluster comes up for a bit.
If u push started again, everything would die. 10 secs or so later , the cluster would come back. That would repeat as many times as I'd hit start button. No starter crank-nothing. When I jumped the starter, it would crank the engine-no start.
