We cant give out info on how to bypass factory anti theft systems.I can help you figure out the problem though.I have never seen a failed anti theft system to cause the car to die while driving.

I forgot to mention that also if you spray starter fluid into the throttle body it will not run either, I checked spark plugs and they get spark, what can you do to help me figure this out

I would do a compression test since it didnt start on starting fluid with spark. So you have a nice blue spark on all the cylinders?

How do you do a conpression check, the plugs were new not super old, is it possible the coil pack went out, or what would cause a theft light to illuminate and not come off ever, I tried all the procedures and relearn but cant get anywhere, can you jump the theft or trick it into thinking its goood

Here is the pass lock trouble tree the injectors are turned off when the antitheft is on. But it should have started with starting fluid.

What make and model scan tool did you look for trouble codes with because the anti theft codes start with a B all the basic code readers I can think of usually dont read thise codes.

I posted the trouble tree for the security light on you need a advanced scan tool that can read more then just the generic obd2 codes to see what security codes you have. That way I can get you the trouble tree for it. There is no trick around it I just a generic obd2 code reader after I left the dealership. But recently I got a advanced scan tool that can read alot more then just the generic obd2 codes and live data for them also.I wish there was a way around a advanced scan tool then I wouldnt have had to buy another scan tool. If you get a noid light you can plug it into each fuel injector harness and crank the engine the engine the light should flash if it doesnt then the security shut down the injectors. Spark is easy to check you get a old spark plug or a new spark plug put it on the spark plug wires then touch the plug to the engine you should have a nice blue spark. Or you could buy a inline spark tester.I would hold off on the compression test right now.I also posted the pass lock relearn like you asked for.

Lets do the cheap part check for injector pulse with a noid light like I was telling you to do. Also rent a fuel pressure gauge from auto zone to check the fuel pressure tester. As far as scan tool to check codes you could get a used one.I bought a used a mac task master which is the same software and functions as the otc nemisys matco pro scan cornwell tech force 2.

Have you checked any of the things I suggested?Also knowing the codes would help out a great deal rather then try to guess why the security light is on.

I dont think you can rent a scan tool that is advanced enough to. Read the anti theft codes. Maybe online you can i. Thought I saw that somewhere.
