2000 Malibu Theft light
 

I have a 2000 chevy malibu with solid theft light.

When a friend had the car she was driving to work and she said the car died when going down the road. I had the car towed to my house thought it was the fuel pump then i seen the theft light on. after going thru some threads on here i replaced the ignition switch and cylinder and did the 10 min relearn with no success. whenI turn the car to the on position and then start it it'll crank for like 5 seconds then start for like 3 seconds then it'll cut off. can hear the fuel pump kicking on when its in the on position then its like when its starts running it cuts off still and the theft light is a solid light it does not blink at any time and will not turn off. all the fuses in the car are good.

not sure what else to try or do any help appreciated.
