The car listed above is a GT. cranks but won't start, replaced all ignition coils, plugs and wires, crank and cam position sensors, new fuel pump filter and injectors, and still won't start. No codes, no security light, not sure if it has any spark. I started it one day and went back inside for 5 minutes and came back out, the car was not running. It would crank but not start since that. Any clue as to what might the cause that after all these parts were fixed?

This sounds like a fuel pump is going out. To be sure let's see if the engine runs on starting fluid, also here is a video to help you check for spark:

If it runs on starting fluid here is how to change the fuel pump out. The following guide will help you step by step and I have included instructions in the images below to help you fix your car.

Check out the images (below). Let us know what happens and please upload pictures or videos of the problem. I also noticed this car has a fuel filter. I would check that first.

It has a brand new fuel pump and filter, and fuel rail has good fuel pressure as well, and won't start on starting fluid.

I can't get pics and videos until next week as the car is stuck at a buddy's house 40 miles away and I don't have the time until next week to go back to it.
