Reset security system

This may be related to the antitheft system The system is known for turning off the starter and/or injectors when it fails. Is there a light on the dash that says SECURITY? This is a common problem worth looking into. http://www.diy-gm-security.com/

There are many symptoms which could cause this problem... electrical, fuel, ignition, etc... determine your error codes and start from there. If the Van has been sitting for some time I would add an octane booster and gas dryer, disconnect the fuel filter and allow ~ 1 gallon of gas to drain into a 2 gallon gas can, replace the fuel filter and see what happens. If that didn't work I would work through the ODB II codes to find the probable cause.

abs not going to be the cause...possible passlock security system problem....does the security light flash rapidly when it wont start? it is common for the security system to act up on these vehicles

try it again sometimes it doesn't work from the first time.first take off the wire from the battery and wait a bit then put it back on and try again

Something in your ignition system or circuit must have quit. The code does not seem to be related. Have you checked for spark?
There is a good read here on the code-a complete run through of what to check.

.there is a good read here on TTT

could have a theft deterrent problems.

find your reset switch and reset it

Most likely the passlock sensor will need replaced and the key reprogrammed unless you recently replaced a key that never got programmed listed below is detail instructions on reprogramming a the passlock to the key.
PASSKEY LOCKOUT RESET ALL GM CARS 1999 AND UP
1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the PASSKEY system to recognize your key.

Ignition keys relearn takes about 30 min to do. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself.

I had this problem with my 2002 grand am. I had a problem with the security system. I had to turn the key forward for 10 minutes until the system reset. When it was reset...the security light would stop blinking on the dash. Then you can turn the key back and try to start it. Hope this helps. I had to take my car to the shop and have something replaced ( can't remember exactly what it was..maybe ignition switch).
