Could a faulty Ignition Control Module or a faulty Camshaft Sensor provoke that Central Port Injector stop spraying fuel?

No, the ignition is its own system.

A scope is the real way to test, not with voltmeter

what is your actual fuel pressure?

THANKS FOR THE ANSWER.
I have open the upper intake manifold plenum and I can see that CPI is not spraying for none of its nozzles, fuel pressure is 60 psi with ignition key on position and when I try to crank it fuel pressure stay the same, only intermitent times CPI is energized spraying all its nozzles and the fuel pressure varies from 55 to 60,
WHAT SENSORS BESIDE THE CRANKSHAFT POSITION SENSOR ARE INVOLVED WITH THE CENTRAL PORT INJECTOR (CPI)?
