in a long nutshell car was running great but developed a miss on way home.got real bad and hardly run when i got home.I hooked up the otc 4000 and it died when the otc went into diagnostic mode.unplugged moniter and would again run bad.I have replaced the module and coil from my other gn and the maf. I have good fuel pressure and have plenty of spark.also replaced the esc on pass. fender.the cam sensor was done a few weeks ago but i cant check it by unplugging it because of the no start....any ideas would be great.thanks PLEASE

I would look at the cam sensor. Do you have another one you could swap on to see if that is it? A buddy of mine got a couple bad ones from Auto Zone. Finally demanded his money back and got a GM unit.

Definitely check the cam sensor, and buy a noid light to hook up the the injectors to check for injector pulse.
