    The 10 minute thing definetly works! Although, I didn't find out about that solution til I was out a car for 5 very long days! My problem is... the anti-theft continous to click on randomly fairly often while I am driving. This usually shuts off after I have re-started the car. I have had it completely lock me out of the car 3x now where I have had to use the 10-min. solution. When I took it into the shop today, they said it was the ignition switch. I find it hard to believe that the ignition switch would have much to do with the anti-theft system! What do you think? Thanks for your help!

Try the 10 minute re-learn:
put key in ignition and attempt to start, let off the key and leave in the run position for about 10 minutes or untill the security light goes out, shut key off and wait 5 seconds, attempt to start vehicle normally, it should start.

    the ignition switch has whats called a passlock or passkey system, when you put the key in and try to start the car, it sends a code to the body control module and the engine control module, the bcm and pcm compare the code to the one in memory and when it is verified as valid the ecm sends a signal to the starter telling it to start. so yes the problem could be the igniton switch, its common on those cars for the ignition switch to go bad.

    I had the same problem. Tried everything I could try. Ran a wire from a 12v fuse under the hood to the hot wire where it plugs in under the car by the left rear tire. Real easy to find. In the plug the is a larger red and a larger black wire. The red is the hot to the fuel pump. Been running like this for almost a year. The security light is on still but it runs perfectly fine.

Where is the fuel reset button on a 03 Chevy malibu

There is no fuel reset button on GM vehicles ! If you have no fuel , your fuel pump or fuel pump relay or the PCM - powertrain control module is bad ! or you have a wiring problem !How do you know you have a fuel problem ? did you do a fuel pressure test ? Do you have a crank no start ? GM Fuel Pump Relay Testing

03 malibu quit while on hwy. Theft light on constant, tried to relearn keys no help. Removed air filter added fuel started and ran until it used up the fuel. Originally thought anti theft but now leaning...

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.

My 03 POS Malibu has had $4,000 in repairs the last few years. Now it won't start after driving! Have to wait an hour or so.

Are there any lights on the dash when this happens? Look for a light that says security or antitheft. If you see this, go to this link. That would explain the symptoms
