Reply to Hammer Time's Post: I've struggled with the security feature nonsense off and on for several years -- it finally stopped happening about six months ago and the light stays on all the time while the car runs.

The light used to blink when the car wouldn't start for several minutes, but this time that's not happeneing.

The car just sounds like it is starting as normal and then dies.

To really find out what's happening here, you would need to have a fuel pressure gauge, a noid light on an injecter plug and a spark tester on a spark plug wire to monitor which function is the one dropping out. The symptoms still have the earmark of a security system overiding things. If you found that it was the injecter pulse that was dropping out and nothing else, that would confirm it.

If you found a different function dropping out, then you would have another direction to pursue.

Reply to Hammer Time's Post: Ok -- you may be right. For the heck of it, I went and tried it again. This morning I get the STUPID flashing security light and no turn over. How can this thing be fixed -- can it be disabled????

Relist: I still need help.
Took the car to the shop - they found and cleared two codes related to the passlock system. WIll these coldes tell a Pontiac dealer what needs to be replaced or repaired? The mechanic at the shop gave me a couple of "maybe's".

Everything is a "maybe" until the component is manually tested and verified as bad. The codes are only telling you about a specific situation it saw. It still needs to be manually tested to be sure. Every code # has a flow chart that takes you through all possibilities for that code and isolates the problem.

The biiggest problem is many of those flow charts refer to using factory tools that you may not have access to.
