My Son's 89 prelude SI was running good for a while then 2 weeks ago started idling poorly at stop signs (even dieing) and now does not run.
- Turn engine over does not even fire.
- You can hear the fuel pump pressurize the system.
- Got good spark. Spray eather into the intake and it runs for the moment.
- Got fuel pressure all the way to the fuel injector rail. Seems like none of the injectors are opening. Checked all wire plugs on computer system to under hood. All good.
- Checked injector resistors and all read 6 ohms.

Every once in while during a start check the engine will fire just a couple of cylinders then no more.

1) Does anyone know if there is a sensor or switch that would kill the fuel injectors?
2) Does anyone have a wireing diagram for the ECU to fuel injectors?
3) Does anyone know how to check the voltage signal at the injector?

Thanks in advance for any comments,
