Re: INJECTOR SOLENOID TEST NOT OK ( *OPEN )

Usually an "Open" Is an wire/pin unplugged or solenoid failed. Always verify the pins are all pushed into the connectors properly at every connection and at the ECM. Do the CAT 5lbs pull test on the wires as well in case the wires have come loose from the pins.

If you have a spare ECM around from same model it wouldn't hurt to try. If you have a blank ECM use the "TEST ECM" mode to try it.

Another way to check is make 2 jumpers to run to neighboring injectors and do the solenoid test. If test fails the same injector number then you know it's not an injector problem but a wiring issue or possible ECM issues. Easy test to do before buying an injector.
