My car listed above 2g (420a engine) cranks but will not start. I have changed the crank shaft position sensor and also the ignition coil. It has fuel pressure but none of the injectors are firing. I was told that the car's main computer is to blame, but I am not too sure. I was wondering could the computer be the problem or could it be something else?

The more common suspect would be the camshaft position sensor, but the place to start is by reading and recording any diagnostic fault codes. Often codes for those sensors do not set just from cranking the engine. They usually need more time to be detected, as when a stalled engine is coasting to a stop. When there is no fault code to direct you to the circuit that needs further diagnosis, you can use a scanner to view the sensors and see which signal is not showing up at the engine computer.
