You need to check to make sure the injectors are pulsing. Hook up a test light to the injectors and crank the engine over to see if the are pulsing to get fuel to the engine. If not you could have a power or ground issue or if that is ok most likely an ignition module problem in the distributor.
Also, I suggets check the fuel pressure when the engine is cold and turning the starter..these must have no less than 60psi... I would think the fuel pump is pulling too many amps and it will not have the 60psi it needs to start.
Other possibiliti, it sounds like the passlock computer is bad or going bad. A bypass wold work, but you need to read a value. Even hough the auto learning one are easy, there is no guarentee that it would solve your problem. When you put the key in ignition, turn it on (not to crank) dos the security light start flashing? If so, you need to either wait 15 minutes or wait with the key oon until it stops flashing. Once it stops flashing, try to start again. You should get to try it 2 times before the passlock will lock up again.
Turn key to start position for 10 minutes and it will reset passlock. Or, once you're tired of being stranded for 10 min every 6 weeks or so, try the following:
Here's the "fix" for '99 tahoe. Took the cover off the steering column, unplugged the sensor from the cylinder *while* the car was running. it's a 3 wire plug red w/ white, orange w/black and yellow. From then on, the car will always start and ignore the sensor. The only negative is the security light stays on. Replacing the BCM only postpones it from happening again if the problem is the resistance in the ignition lock cylinder. Check out the following links: gm-passlock-ii-system
