    I have a similar problem with my 2007 Malibu. When I set the alarm system with the click of the button, sometimes, usually 3am is when the alarm decides to go off for no reason. I find that when it rains it happens more often. At times when it's "possessed", the doors won't lock, horn goes off, lights flash. I would love to know how to bypass this annoying problem. When I leave town, I manually lock my doors and disconnect the battery so my neighbors won't hate me !

    My 99 malibu will not start after being driven. it will crank but not start..the security theft light also comes on. After it sits for 15-20 minutes it will start right

    my car also has this problem (2002 malibu). It suddenly would not start and the shop told me it was the anti-theft system. I would need to replace the entire ignition system to fix it... so I'm dumping it for a new car.

    Same problem 2002 Malibu, turn the key to the on position and then leave it for 10 minutes. it resets the computer. after ten minutes the theft system light will stop flashing. turn the key off, then start the car. It works everytime for me.... however very annoying and sucks when you are late for work... otherwise the chip is $300. I've replaced it twice....still have to manually reset it.... disconnecting the battery cable does not do anything......

    Most guys I've met have this same problem and it is bloody annoying. There MUST be a way around it. I don't want it on my car anymore (I bought it for $800).

    Same thing. If the theft light goes on I cannot start the car for 10 minutes until it goes off and stops blinking. Very annoying and the chevy people ignore you.

No, I think he has the same problem I do. I have a stock 99 real theft system. Usually after it rains or gets cold, a "theft system" light comes on in my dash. I can be driving, and the light will come on. If I turn the car off, I cannot restart the vehicle till about 20 minutes have passed and the light finally goes off. Sometimes this light comes on when I try to start the car in the morning. I put the key in the ignition, and the car will not start for 20 minutes till the darn theft system light goes off. From what I gathered, the theft system issue has something to do with a "passlock II" defect. I have no idea what this is, all I know is that I can't get a mechanic to listen to me, because the issue never repeats itself when I go to a garage. It gets a little annoying, but I've learned to deal with it.

    If you were really a Chevrolet Wiz you would know the Malibu has been plagued with this problem since the 97-98 model. So please do some research or field experience before not contributing, and just annoying people with your ignorant comments.

SOURCE: Fuel pump won't run Theft system shows P1260 code

It sounds like the computer chip in the key is bad. They get damaged really easy and that will cause the fuel pump to stop. If the "Theft" light is flashing continuously when you try to start it, that is the problem. You should be able to get a new key from the dealer or off ebay, and have it programmed. Should be under $100.

I have a 1999 sunfire gt and it starts runs for a second and dies,my anti theft light on my dash is not blinking it just stays on,does anybody know a way to bypass the anti theft so that my car will r

Yes, unfortunately this is very common on GM vehicles. Go to this link for everything you need. Rule of thumb is this. If the light is flashing, the problem will be In the ignition or the smart transponder key. If the light is solid, the problem is in the TDM (theft deterrent module). This is the main computer for the theft system. There is a full bypass method on this link listed under PERMANENT FIX. This is what you will need. It will bypass every aspect of the system 100%.

When anti theft light is blinking the car wont start. Can you bypass the anti theft device

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.

No start cranks but does not fire has spark. has fuel if bypassed by relay fuses good new fuel pump a year ago has fuel replaced battery froze, has prostart remote start, been in 8 years no issues 2000...

check to see if the security light or anti theft light flashes. if that is the case, sounds like the bypass for the remote starter may be causeing the no start by tripping the anti theft system. Remove remote starter and bypass system and join any cut wires back together that may be cut for remote starter. Try starting, if theft light still flashes leave key in the on position after attempted start for 15 minutes till theft light goes solid, turn off and try again. Repeat process for three times to re-learn factory theft system in vehicle. If problem still persists, then take to your local dealer to reprogram factory theft module in the cluster.

There is a thing called the Passlock system which is the anti-theft system. You can get a passlock bypass module really reasonable to use. It comes with instructions as well.
