Have you check if the spark is present? What about the fuel? If you have both of them, you should at least get the car firing up.
Let us know how you get on.
Cheers.

this car uses the VATS/PassKey system, which is turning the security light on when you try to start it.

One possibility is that the resistor in the key is damaged or dirty. If you have another key, try that. If the chip in the key wiggles or the contacts are dirty, that might be the problem.

If it's not the key, you might need some electrical work done on the security system to get it running again. If you're good with electrical work, you can get wiring diagrams (Haynes repair manuals include them) and try to do it yourself.
Most likely your VATS system has an issue and it is not recognising the key and since the light is staying on, that is more evedince thay this is going to be the issue. I am going to do some reading and see what we can do to by pass that if possible on your car.

When you turn the key to the start position, check to see if you have power at the "s" terminal on the starter. Also, be sure you have power at the larbe terminal that comes from the battery.If you are not getting power to the s terminal, the vats could be the problem, or the neutral safety switch also. If you are getting power to the s terminal on the starter, with the key in the start position, a faulty starter would be indicated.

Camaro died, changed fuel pump and relay and still nothing. It clicks and doesn't pump


It's that infamous "chip" in the key that becomes a nightmare to many. The security light may or may not start flashing. Sometimes it stays on steady. Gradually the car begins not cranking anymore or if it cranks it will start and die in a second. Randomly it will do this more and more often until it won't start anymore. VATS, PASSkey and Passlock immobilizer systems are killing cars all over North America, they have a short lifespan and are certainly more effective against owners than thieves. Here is how you save your car
QUICK FIX TRICKS
1st trick, Try a spare key that is newer or used less. The pins wear down with use and so do the keys causing the security to fail.
2nd trick, (if not starting) turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start. I did this in my regal for more than a year. If its shutting down while running, I'm sorry I have no quick fix...
CHEAP FIX: Bypass the chip in your key. This is temporary, but effective until the TDM (theft deterrent module) in the dash poops out. Then you're kinda screwed. I was told that these types of key security systems have a 7-10 year life span. Sucks for us. This link explains the "Key Issue" pretty well.
----- http://vats.likeabigdog.com/

If you're gonna tear your car apart anyway, just do this next fix and bypass it all together. Its more money, less work, and a PERMANENT fix. Up to you tho.

NEVER WORRY AGAIN FIX: Bypass the whole VATS/Passlock/passkey I or passkey II system entirely. Literally take it out, and throw it away. I just did this in my Regal. Took about an hour. It took longer to find the solution than it did to fix the problem. They sell a unit for 200 bucks to totally bypass this system FOREVER. life time-money back and all that. Finally did this in my car. Well worth the 200 if you've looked into getting this replaced... It can cost anywhere from 600-1000 bucks. If you do buy this, please purchase it thru this link.
----- http://newrockies.ca?ap_id=judd0081 ----- With this fix, you can take that whole Vats, passlock, passkey system out of your car all together. Good info on both sites.

It works for:
Any GM or Isuzu Vehicle with VATS or PASSKey or PASSLock security systems.
If your car has the chip in the key or in the lock cylinder, then you can save it with this Full Bypass.

The problem is your Vats security system. This causes the car to either "not start" or "shut down" while running. (depending on the system) If the security light flashes, i guarantee that this is what the problem is. 1st trick, turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start.

The VATS system has 15 possible ohmic variations in the key .One might use an ohm meter and measure the resistance in your key as this is simply a resistor producing an ohmic value which must match the resistance value the VATS module wants to see. There is a 2 wire key reader in the ignition cylinder that sends this signal to the VATS module looking for a match.One may surf the web and see ways to bypass VATS but I have never tried this and its is fairly sophisticated process which requires an accurate DVOM meter that reads OHMS
