Will it let you know if injector is clogs or leaking? Can you see a spray pattern?

it pulses the injectors individually with 3 different pulse rates, that's all it does. it has a ford connector with 2 extra wires for different connectors. have to use it in conjunction with a pressure gauge.

What is the difference between ultrasound and this button? ? What does the injector mean and how is this button tested? Is there an explanatory manual

there is a explanatory manual..

Want to test a jeep motor, does it have the ev1 or ev6 style connector?

I bought a "universal" connector separately; but, as illustrated, this unit includes an alternate connector consisting only of two female pin connectors (almost all injector connections are male), which can connect to on any injector (polarity doesn't mater).
