Hi, welcome to the forum!

PCM stands for Powertrain Control Module also known as "the computer". It controls all the functions and sensors of the engine and transmission.

If you can't hear the fuel pump priming and you have already replaced all that, check the inertia switch. If you have power on one side but not the other make sure it isn't triggered (push the button on top of it). If it's OK then it might be defective and you should try disconnecting both wires and jumping them with an extra wire.
