You are correct twice. The antitheft is failing and turning off the fuel injectors. Go to this link for help. This is a classic GM problem and totally 100% related to the antitheft.

Try this I got it from the emission wiz
Put your key in turn it on dont start wait 10 mins remove key wait 10 seconds repeat this a total of 3 times. If that dont work try a different key do the same thing. This relearns your key to the ignition it started with Gm cars and trucks from 1999 to to 2006. It is a big problem but there is no recall that I know of. If that dont work a dealer needs to probably replace and reprogram your ignition switch and keys

SOURCE: When anti theft light is blinking the car wont

On a 2003 Chevy Maibu the theft system light comes on and blinks when the system is triggered. The car will not start and the fuel pump cuts out. You must turn key to on and have all doors closed. Keep the key to on for 10 mins til theft light turns solid and then disappears. Then turn key to start and it should fire up.

My antitheft light is blinking and my car wont start. What should I do?


The relearn procedure is simple, but takes a little time. 1. Try to start the car. When the car doesn't start, release the key and leave it in the run position until the security light quits flashing (usually between 10 and 15 mins.). When the light stops flashing and goes out, turn the key to the off/lock position for 3 seconds, then the car should start.

I have an 03 chevy malibu that i changed the oil & filter and went to start the car and it would not start and the security light is flashing what can i do?


The Passlock system is not recognizing your key. If you have a second factory key, try using that. If it doesn't recognize either key, you will have to go to a dealer to get a relearn done. :o(

2003 malibu won't start. Will turn over fine and it amost starts if you leave it for awhile. Hoping its just fuel filter. If so how do I replace it ?? Thanks.


I just had this on my car too. Turn the key to "on" without starting the engine. Look at the display and see if the Anit-Theft light is blinking. If it is, you need to keep your key in the on position for about 15 minutes until the light stops blinking. Start the car when the light starts blinking.

99 GMC Sierra Pickup: Crank but no start. starts with starting fluid but dies. changed out the fuel filter. still not start. Do I have a bad Fuel Pump? Security light flashes then goes solid after 10 min....


The theft light issue is a good observation. Have you replaced the key tumbler or an ignition component lately? Has there been a lightning storm close very recently?

What the flashing security light is indicating is an attempt to relearn the key you are using.
Turn the key to run position, allow light to flash for 10 minutes, when light stops flashing turn ignition to OFF position for 5 seconds, turn ignition to run position and start over. Do this for 3 consecutive cycles, the the theft system will relearn the key cylinder code and store it once again.
Try that first before you go any further.
Let me know what you find.

Starts but quits


If the engine starts and then quits when you release the key to the ON position it could be the anti-theft systemhas locked out. Turn your key to the ON position and wait ten minutes until the ANTI-THEFT light on the dash board goes out. The car will now start and run if that was the problem.
