You have already replaced the pcm but still am not getting power tothe coils or the fuel system What is next?
Depending on the vehicle, you could have a alarm or security lockout happening. There is a relay in the circuit that is not allowing these items to operate. There also could be a wire broken (a short) that is not allowing the pcm to get power. You have not specified whether you are getting power to the pcm or not so you will have to get a meter or test light out and see if you are, and if the is not power there, then follow the wire or schematic and find the fault.
Can you crank the engine?
Have you check the relay for the fuel pump?
Have you checked the power for the fuel pump relay?
