There are times when attempting to start (usually when warm ) it will turn over but not fire. When the ignition is turn on the anti theft light is the only one on. If I turn the ignition on & off a number of time or wait the other ignition lights will come on and it will start. It has stalled on interstate driving a couple of times. Again the only light that comes on is the anti theft light. If I wait approx 10 minutes and try starting it will start & run again. I have incurred $ 800 in GM mechanic qualified repair bills to no avail. The crankshaft position sensor was replaced & relearned, the fuel pressure regulator was replaced & the ignition module was replaced to no avail. i have tried a different key. GM mechanics say they don't have an answer. On one site there is a discussion of the GM pass lock system. What is the story---can it be disconnected?
