Fuel pump and injectors are not kickin on but I bypassed the fuel pump and it turns on, the engine rotates but car still wont turn on, I then pulled off injectors and there is no fuel passing through. Could it be a sensor or?

Assuming you do have spark. Check the inertia switch, usually in the trunk.

OK I don't know your level of expertise, but to test the switch, remove it from the car, shake it until it trips, then test continuity between the terminals, there should be none. If it passes reinstall it, then reset it. The other part of this is are there any stored codes? Test involves with and without codes, a bad ignition switch can crank the engine give spark but no fuel. If codes are stored, get them read if you can, or buy a cheap scanner, they can be had for about $40.00, a great investment since all cars sold in USA from 96 to present can be scanned for "P" codes.

Have you tested the wires at the connector? If they are dead, trace them back, you may find a break in it, if there is power, then the pump is dead.

BTW what is the security light on the dash doing when trying to crank? It should be off!

If you changed the ignition switch is it possible you damaged the transponder wires?

Test wires between PCM and CCRM, check the connectors...

where is the pcm located at?
Behind the right kick panel. Think about getting a shop manual for this car!
