My 01 Malibu has the no-start problem too, although I am not sure if it's the passlock issue.
Here is the sympton:
1. if I turn the key to on, the 'theft system' light comes on, steady, not blinking; all the gauge don't work, dashboard lights are out. But I do have power, I can roll the window up and down, cd/radio works.
2. Continuing, I don't hear the fuel pump noise, and certainly it won't start. Sometimes when I get lucky and leave the key in there for a while, the dashboard lights come on, all gauges back to normal, 'theft system' light goes off and I hear the fuel injecting, then I can start the car
3. In one those 'lucky' days, sometimes the engine stalls when I am driving. It has happened 4 times, all after I make a turn, left or right.
I know this doesn't sound 100% like the passlock system, but could anyone please shed light? Could it be ignition switch or BCM?
