How do you test the CPS?
A vacuum gauge will not work to test fuel pressure. You need an actual fuel pressure gauge. To test the CPS you need a logic probe. You the pin the CPS input on the ICM and turn the engine over and see if the light it blinking. (You have to do this when the car won't start)
