I believe that if you hook a noid light to the injector plugs one at a time and they flash when you crank the motor, that proves the crankshaft position sensor and ECU are good. So as long as you have good fuel pressure and since you changed the coil pack, the problem is probably the ignition control module. You can actually check the fuel pressure at the fuel rail port with a tire pressure guage. Pressure shoure be around 42 psi with the key on.
I don't think it can be the cam shaft position sensor as it doesn't come into play below 400 RPM. Or until the motor is actually started and running on its own.
