TCS Wont come back on after cam install help!!

Ok we just got done installing the cam about 2 weeks ago and since then the TCS light would com eon with the car, but after i start it up, as soon as the airbag light would finish blinking the TCS off would automatically come on and i cant turn the TCS back on.....

We've checked almost every possible thing including changing both sensors on the rear tires, checked all the sensors under the car and going into the rear, changed the abs module, tested the PCM, even tried to delete the code but would come back after 3 seconds and we used the GM master tuner computer module...still nothing... Tommorw were going to try and swap out the PCM with another 02 PCM and hope that works...if not i have absolutly no idea what it could be....

It worked before we put the cam in but i didnt touch anything that could possible screw up the TCS.....

Any suggestions would be greatly appriciated because i'm could to check again for the problem tommrow!!!

My best idea...

Although I hate the stealership as much as the next guy.

Did you remove the module at the front of the engine bay for any reason (i.e. to get the cables out of the way?) The canister looking thing near the battery.

No the module wasnt moved at all.... believe it or not we found the problem... It was the damn PCM!!!!! Dont ask b/c i have no idea but it just must have been a freak timing thing because it was never touched and the battery was totally disconnected during the install so i guess it just went of natural causes....:lol:
