P203 Open Circuit injector 3 Error Message?
 

Tested electrical connector with Noid light and it flashes, so I tested the
impedance on the injector, was 13 ohms. So I replaced it, put everything
back togather and still get the error message. Has anyone had this
problem before? Can't figure out what it could be if the electrical is putting out a good signal and it has a new injector? Puzzling. This is on a 3.2 Liter
engine, so I am working on the middle cylinder, passenger side, which is
what my haynes manual says is cylinder 3. :confused:

I wonder if the injector electrical connector might not be making proper contact to
the fuel injector? Had this happen once on a electric window control, the tabs were
spread out and not making contact. Anyone know where I can get a new fuel injector
electrical connector for a 1997 3.2L Rodeo?

New connector didn't work. Puzzled. Noid light works, new injector, new
electrical connector - still same error message. Must be the ECM???

Anyone have any ideas?

bringing up post on getting a connector whats part number , brand, make/ model to look-up. actually will be the same as rodeo connector but it is for the amigo 98 3.2l v6. did you look up rodeo... or the connector or.... i have delphi ppa stamped on it but cant find a one connector, you didnt hve to get whole harness did you?

P203 Resolved - broke wire on harness
 

Tunred out to be a broken wire where the harness goes from inside the
engine compartment into the inside cabin. The wire was rubbing and
became partially open when running due to vibration. Crazy - this was
a hard one even though the car was telling me it was open - just a very
hard location to get at to fix and isolate. Wow -J
