Z31 VG30ET not starting

Hello guys,
I need some help on my newly bought Z31 1984 Turbo.
What I know and tested:
  • Car is completely stock, has been standing immobilized for 20 years but is cranking.
  • I have spark so I suspect crank angle sensor is good.
  • It starts on carb cleaner injected in throttle body.
  • New fuel and pressure is good(tested).
  • ECCS LED are ON when ignition is ON and has no error codes.
  • Injectors connectors have 2x 12v on the wires when ignition is ON.
  • There is no pulse to injectors when cranking.​​​​​​​
​​​​​​​Any suggestions on how to proceed from here?
thx

The Crank Angle Sensor (CAS), if not working, will result in a no-pulse situation. Have a look here for troubleshooting/solution. Really hope this helps.
