What Mike S said. The pulses that drive the injectors are too brief for your basic meter to capture and display. You'd need a fancier "peak hold" meter or oscilloscope to properly measure them. What you're seeing suggests that the injectors are being driven, confirm by checking for spray, as Mike S suggests. The subject was discussed here less than a week ago, and some procedural and safety tips were mentioned. -- Mike "Rocket J Squirrel" Elliott 84 Westfalia: Mellow Yellow ("The Electrical Banana") 74 Westrailia: (Ladybug Trailer company, San Juan Capistrano, Calif.)
