CHEVROLET BLAZER FUEL PRESSURE PROBLEM

1995 Chevrolet Blazer • 180,000 miles

1995 Chevrolet Blazer 6 Cyl, 4 WD 4.3 Lt
V.I.N 1GNDT13W4S2258048
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 up fuel pressure stay the same, only intermitent times CPI is energized spraying all its nozzles and at the same time fuel pressure varies from 58 to 60 psi,
WHAT SENSORS BESIDE THE CRANKSHAFT POSITION SENSOR ARE INVOLVED WITH THE CENTRAL PORT INJECTOR (CPI)?
