Important.

Remember to follow all the safety instructions given in the repair manual (Procedures secction), and in particular never to come near with lamps or devices that could give off sparks or electrical discharge.

To carry out the test correctly, lower the LPG pressure upstream of the injectors to 5 bar or below. To do this, proceed as described below:

Disconnect the LPG solenoid connector on the pressure regulator.

Set the Gas / Petrol selector to Gas.

Start the engine and wait for the system to switch over to LPG, and then back to petrol.

Switch off the engine.

Connect up the Examiner diagnostic equipment set to 'Control Units' test.

Enter the 'Parameters' environment.

Check that the 'Gas pressure' parameter is 5 bar or below. If the pressure is still high, repeat the cycle.

Disconnect the connector (1) of the injector being tested.

Remove the fixing clip (2) and remove the injector (3) from its seating, with the pipes connected, making sure not to damage them.

Immerse the nozzle of the injector being tested in a container containing a soap and water solution, and check that there are no leaks, made evident by the continuous emission of little bubbles.
