The theft system icon came on the dash while I was changing my battery out. The car acts like it want to start when I push to start the car but it just try to turn over like its going to start but it doesn't. It drained the battery so I went and bought a new battery for it and it drained that one as well. I've had the starter and the fuel pump checked and they both were fine. It sounds like its not getting any gas when it tries to start but it is getting gas just not turning over completely
Please help me

So with the key in the run position is the security light on solid or flashing? I need to know that first and if so was that why you ran your battery down from trying to start it with the security light on solid or flashing.

The security light comes on and goes off. When I push the push to start it tries for 10 seconds then it stops. The more I try it the slower it tries to turn over.

If the security light turns off then I dont think the security system is keeping it from starting. Have you checked for codes yet?

There are no codes, I'm assuming since the car tries to start and don't completely turn over, the codes aren't registering.

I had it checked and nothing shows up, Before this issue I had a code that was the 02 sensor, I had that replaced and the car only started once after that.
