Opti, Plugs, Wires, Coil, Coil Wire have been changed and still the car will not start. It cranks and cranks and cranks. Anyone know if what might be wrong? What else can i tell him to check? Fuel Filter mabye?

Maybe fuel pump. Turn the key but do not start. See if you hear the pump priming.

Talking

Turned out to be the ICM (Ignition Control Module) ...starts like a charm now.

I was gonna say, missed the ICM... Glad you found it now... At least the boss's ride will be good for a while now...
