Malibu Problems

:banghead: I am having a problem with my 2005 Chevy Malibu starting.It has no problem cranking over but it won't start. I recently had to call a tow company to use a slim jim on my door because I locked my keys inside.I was wondering if maybe a anti theft switch was tripped or something. Any help out there would be greatly appreciated.

Have had the same problem with afriend of my wifes 2004 malibu. I have change fuel pump and fuel Pump wirring harness for her and it still doesn't start from time to time. My next guess would be ignition.
