Dont know terminal is which but you have 4 for camshaft position sensor(2 grounds, 1 power and 1 signal it looks like) 4 wires for spark control (1 power and 1 ground for the primary coil transistor and then 1 power wire straight to the coil primary winding and 1 wire going into an external resistor)

is this correct? i have crank, no start,

i removed injector assembly and watch my fire event all 4 injetor fire the same its not fire 1-3-4-2 is it Good?
i have spark but, sometimes lack of spark. i dont know the optical sensor is BAD.

i already check my wiring.
here what i have. i dont know how test inputs to distributor .
i have 5 wire on my distributor. and 2 wire

this is my INPUTS?
- black/white - ? (i have 2v readings when i rotate rotor)
- white/black - ? (i have noting )

CAMSHAFT SENSOR
- blue - 5v SIGNAL pull-down design
- white/red - 12v
- blak - ground

POWER FEED And RPM

- Black/red - 12v Power feed
- green - RPM

thank you guys i have photo's below

Black/ White is CMP signal. Blue is 5v Ref. White/ Black should be Power transistor control wire. If you connect a test light to batt + and touch on that wire either at the ecm or at the connector with engine cranking, you should see the light flicker.Since you stated that you have Spark and injector pulse, it is expected to see a pulsation there. Also, there is a Black/white going to the ignition coil. I am not sure if we have the same diagram though.

It's normal.

From Mitchell1's Theory & Operation for Nissan Sentra

Sequential Fuel Injection (SFI) SFI vehicles can operate in one of 2 injection modes: simultaneous or sequential. In simultaneous injection mode, fuel is injected into all cylinders at same time. In sequential injection mode, injectors are triggered in spark plug firing order. Fuel injection operates in sequential mode under most conditions. Fuel injection will shift from sequential to simultaneous mode under following conditions: when engine speed is less than 300 RPM, when engine temperature is less than 140°F (60°C), and during starting.

Even in sequential mode it may not be fully sequential has know it on more recent engines, instead it will be semi-sequential ie companion cylinders may be fired together

It may also be worth cleaning the optical trigger wheel.

ISTR there is a Youtube video on trouble shooting this type of Nissan ignition --- but I haven't hound it yet.
