#2 Fuel injector signal dead. 900 1991

Have you switched the plug from another injector to the so-called-faulty injector to test if its the injector itself or the plug connection thats defective. Look for "pushed-in" terminals inside the injector plug too. These could be repaired. Whats the condition of the injector wire? Any breaks in insulation etc?

The wiring scheme is that ALL injectors share the same signal from ECU. In the ECU there is only one transistor (not MOSFET, yes I've studied several 900 series ECU) driving ALL the injectors simultaneously. The injector plug connections are interchangeable only limited to wire lengths.

Regards,
Amarin.
