Well update: F'ING dealer
they would not diagnose the no start condition due to aftermarket accessories...Remote start,HID's WAI etc. They are jackasses!
I called up the place that installed the remote starter when I bought the car in 2001 & they said that possibly the resistance changed for the passive system & they would adjust it if needed. I told them about the dealer problems & they said that the GM dealers got a memo from GM to decline any warranty work due to mods. The dealer will only perform work when mods are removed from the vehicle.
That is the last POS GM vehicle for Me as I am more & more leaning to buy a import even thought I hate imports
Oh yeh,get this...the place that I had the remote starter installed "D&R Auto Restylers" does some work for the dealer installing remotes in NEW CARS!
The installer said that GM products are a B**ch due to the POS passive system. They install for Mercedes,Lexus etc. so this installer is no sloach.
