I installed a new pcm and was able to successfully do a CASE relearn. Now I am having start problems, as in not at all. It turns over & wants to crank but it is a no go. I've disabled the VATS & still nothing.
After scanning the PIDS, it seems that in the VTD there is something enabled with regards to the fuel system whereas everything else is either disabled or no in the field.

I've searched through some older threads & some have dealt with various codes like U1255, but didn't really have a clear post for resolution. It seemed it had it one day & the next few post all was resolved. :?
HELP! HELP! HELP!
