I think the black/yellow wire should be getting constant 12V and the other wire has power only when the ECU turns on the injector.

The YEL/BLK wire should have battery voltage with the key in ON(II). The other wire runs to the ECU, which provides ground for the injector circuit with the proper timing.

Re: fuel injector question

Bump since im tired of this kids car not working. Is there anyone who had this problem with both the ground and power wires getting constant 12v power?
