Changed Ignition Control Module. Added toggle switch to override Anti-Theft possible Anti-Theft problem. The car ran for a few days then back to not starting. Replace Ignition module and cylinder. No change. I found low fuel problem, replaced the Fuel Pump and inline filter. The car still will not start and I am at a complete loss to know why. No answers online or from local mechanics.

When trying to start the car does the security light flash? If so, the car immobilizer has kicked in because of the bypass. If not, when you turn the ignition key on without cranking the engine on do you hear the fuel pump running inside the fuel tank? This guide can help as well:
