Check

PERFORMANCE ORDER

1. To check injectors, start the engine and apply a special stethoscope to each of them. If you hear clicks, so the injector functions normally. 2. If the injector does not click, connect a special lamp to contacts of a wire of each injector. If the lamp blinks, so on contacts of an injector the correct tension moves. 3. Kill the engine, disconnect wires from injectors and measure resistance of each injector by means of an ohmmeter. Compare the received results to technical requirements.
