I see the wires are different colors but the terminals on the injectors are the same orange. Is it possible to get them mixed up if you pull them out trying to clean them and for get which wire went to which side? Let me know, ive got one injector driping fuel, the other not spraying at all.

 

As far as the wiring goes, there's no polarity on the individual injectors. To the electronics, they're just a coil that looks the same from either end. ASSuming there isn't a short or open in the wires going to the injectors *and* the connectors are on securely, your problem isn't with the connectors......

 

okay thanks!
