I even replaced the PCM and it won't start. please help

Good evening,

Can you hear the fuel pump come on when you turn the key to on? I would check the fuel pressure. Running out of fuel ruins the fuel pump as the fuel is a lubricant as well as a coolant for the pump.

Can you see an RPM signal on the dash when you crank it? That will tell me if the crank sensor is working.

I would also do a compression test as well.
