1989 Jeep Wrangler, Injector Waveform
Posted to the Waveform Library on 4/6/2005

When this jeep failed to start, I had no fuel spray from injector. I did a current ramp of the injector and found this wave. I suspect the injector is physically stuck, drawing full amperage for the full on time in attempt to lift the injector from it's seat.
