I have a tech2 clone. I set it up along with a fuel pressure gauge to test the injector balance. I get the error message "voltage out of range" when I try to initiate a test for any given injector. I have the ignition sw set to "accessory on", but there is no run position w/o starting the engine. SO, there is no 12 v applied to the injectors before, or when, the test is run. I don't even get a fuel pump enable so that the pressure can build ahead of pulsing an injector. Is there a setup step I am missing? Anyone know?
