Trying to get an '81 Vette(Not mine!) to pass AZ emissions. It's got all the wrong parts on it( it's from Nevada), mild Lunati cam, Edelbrock 1406 non-emiss carb, vac advance distributor and an inoperative AIR pump system. I don't believe the airpump is correct, but the computer isn't sending signals to the solenoid valves on the pump. Does anyone have a vacuum and electrical diagram for the AIR system, ot just a pic of what it should look like? Thanks!
