Chevy Malibu 2005 4 cylinder will crank but won't start. this is an emergency!!! please help

Anti theft system light blinks car won't start, crankes but won't start help?

I had this problem a million times. Faulty ignition, isn't recognizing your key. To bypass pit into on position and let sit there for ten minutes until anti theft light turns off. Then return key to off, remove, and restart. Should start right up. Alternatively you can disconnect the battery to reset the anti theft lock. Hope this helps. Took me a lot of searching to figure this out. Turns out it's right in the manual. Bypass anti theft

Could have a clogged fuel filter or fuel pump could have gone out
