4. OPERATION
NOTE:Before using the tester, inspect the adaptor connections
and return flow connections for obstructions, as these
could considerably increase the pressure in the injector,
possibly causing damage to it. Ensure that the fuel system
is NOT pressurised, refer to the vehicle manufacturer's
instruction manual.
4.1. Setting up the tester.
Fit one of the gauges to the main body, the 15 Bar gauge for
Bosch and Siemens systems and the 3 Bar gauge for Delphi
systems. Ensure that the drain valve is in the Off position.
4.1.1. Disconnect the return line to the injector that is to be tested.
4.1.2. Connect the return line to one of the return flow connectors and
connect the other end of the return flow connector to one of the
connectors on the main body of the tester.
4.1.3. Connect one of the injector connectors to the injector and the other
end of the injector connector to the other connector on the main
body.
4.1.4. If testing a Delphi system, use the brass cone for the return flow.
4.2. Testing an engine that will not start.
4.2.1. Briefly operate the starter motor several times so that the
transparent sight glass is filled with fuel.
4.2.2. Operate the starter motor for ten seconds, at the same time read
the pressure or vacuum reading on the gauge. Compare this
reading with the manufacturer's data and rectify problem if required.
4.3. Testing an engine that is running.
4.3.1. Start the engine and allow it to run at idling speed until the
transparent sight glass is filled with fuel.
4.3.2. Read the pressure or vacuum reading on the gauge. Compare this
reading with the manufacturer's data and rectify problem if required.
4.4. Removing tester.
4.4.1. Turn off the engine. To depressurise the fuel system, place the drain
pipe into a suitable container and open the drain valve. When all
fuel has drained out, close the drain valve. Dispose of the fuel
responsibly or re-use it.
4.4.2. Remove the connectors from the main body, disconnect the
connectors from the vehicle's fuel system and reconnect the return
line to the injector. Ensure all tools and kit parts are removed before
driving the vehicle.
