Default Causes for injectors not spraying?

I have fuel to the rail, spark, compression, the motor cranks but it wont start. I am getting power to the injector connectors 12.5V on the one wire and 3.9V on the other. The injectors wont spray though. I kept cranking, checked everything, took a plug out to smell the cylinder for fuel and nothing. Pulled the rail off and cranked it nothing came out of the injectors. What causes them to not work? The ECU was perfectly fine last time it was running.

What trigger a fuel injectors to spray when start-up? Crankshaft position sensor! If your motor is 95 or below , check your distributor. If it is a 96 or above, check the sensor behind the timing cover. when it is cranking it should read 1-3v, not exactly remember but not 5v steady.

Check whether ECU terminal A23 is providing ground. If so, swap in a known good ECU.

ECU fried or ground bad or cam sensor I think one has to be the problem, maybe all IDK. No spark on 3rd cylinder also now, my cap and rotor are burnt a little. The reason I say cam position sensor is the motor needs either a crank or cam position and JDM motors have a cam not crank. It needs to know where everything is for the duty cycle to know which injector to open. The cam position sensor is located inside the distributor, maybe something fried hence the burnt cap and rotor and 3rd not sparking and maybe it burnt up the sensor? How should I check the ECU to make sure its grounded? Before I go buying a bunc of things I want to try and check everything to see exactly what needs to be replaced.
