CHEVY WON'T START

1998 Chevrolet Blazer

Electrical problem
1998 Chevy Blazer 6 cyl Four Wheel Drive Automatic 120000 miles

1998 blazer with a 4.3 v6. Ran fine when parked, 2 dats later it had dead battery, gave it a jump start and it starts and quits 2 or 3 seconds later. Also noticed the the security light on the dash is on. I'm guessing the one has something to do with the other. Is there some way to reset the system or is there faulty part I need to replace? Thanks

PASSLOCK Reprogramming Auto Learn
You must perform a Passlock™ Learn Procedure if any of the following components have been replaced: • Passlock™ sensor

• Body control module

• Powertrain control module

• Vehicle control module

Both of the above modules except for the Passlockâ„¢ sensor must be programmed using their own vehicle configuration. See the individual module service manual section.

There are 2 types of Passlock learn procedures: • A 10 minute procedure which requires a Techline Terminal and a Tech 2 scan tool PASSLOCK Reprogramming Seed and Key.

• A 30 minute procedure which requires a scan tool used in order to clear codes. This procedure is listed below.

30 Minute Procedure
Ensure that the battery is fully charged.
Use a scan tool in order to clear the Passlockâ„¢ DTCs.
Turn the ignition switch from the OFF position to the CRANK position, and then to the RUN position.
The vehicle will start and then stall.

Leave the ignition ON until the security telltale turns OFF in 10 minutes.
Repeat Steps 3-5 for 2 more times (3 times total)
The Passlockâ„¢ controller will learn the new data on the next start attempt.
Use a scan tool in order to clear all DTCs.
