Your car has a passlock problem. Passlock is a factory security system, and the security light is the indicator of a problem.
Try this to get the car started--turn the key on but do not try to start the engine. After about 10 minutes the security light will stop blinking -- this indicates that the passlock system is on by-pass. Turn the key off for 6 seconds. Then try to start the engine. It should start.
The passlock problem is most likely a bad resistor in the ignition switch but you should take the car to the dealer so they can test the passlock system.

 If you cannot bypass the passlock then there is a malfunction in the system. This usually requires a trip to the dealer or a mechanic that has a tech 2 scan tool (or equivalent). Try changing the battery in your key, but that is a shot in the dark.  Keep me posted.

The shaft lock is spring loaded, I can usually press down hard enough with my hand to access the retaining ring, Then use flat bladed screwdriver or something to work the retaining ring up out of the groove and off the end of the shaft. Because the retaining ring is split, you can work one side at at time. If you can't push shaft lock down far enough, they make a tool for that.

I don't know, guess I'd have to look at it, the diagram is what my database showed? I'll look again.

Have you tried spare key (if available)? If starts with spare key, destroy key that does not work and have another made. If does not start with spare key, replace ignition switch.

Does your key have a black thick end on it? If so, you will have to go to local locksmith or local Chevrolet dealer to have the key cut and programmed, becuase it has a chip inside if it has black end. If it does not have chip then a locksmith can cut the key. A regular key usually costs around $5. A programmed key is much higher, usually around $150.

No problem. You can also read our CAR REPAIR TROUBLESHOOTING page about this issue. You can find the link below..

Perform all of those tests before purchasing anything. This will help save money by eliminating potential culprits so you don't end up buying parts that are not needing to be replaced.

I would check the fuel pressure. It sounds like you have a failed fuel pump.

You mean the gray wire at the fuel pump? If it does not have power, and it should for only 2 seconds with key on, check the fuse for the load side of the relay.
