2002 Chevrolet Malibu fuel system problem

Initially started with fuel gauge dropping to E, which was diagnosed as the sensor on the fuel pump. Then it started to idle rough, now it will crank but won't start. Its getting fuel up to the injectors, though it seems like not enough. The fuel pump engages when ignition is turned. And the anti-theft light is flashing

If the anti theft is flashing, it sounds like it has the system shut down. What I need you to try is this. Turn the key to the run position and allow it to sit for 10 to 15 minutes to see if it overrides the anti theft. If it doesn't, then I will need you to check for spark, if the fuel pump pressure is within the manufacturer's specs, and if the injectors are getting power.

Do this and let me know what you find. Also, if you have some starting fluid at home, see if it starts when you use it. That will help me answer other questions and I will need to know if the check engine light was on prior to the issue.
