- testing and adjustment

1 Check the earth wire connections for tightness. Check all wiring and electrical connectors that are related to the system. Loose electrical connectors and poor earths can cause many problems that resemble more serious malfunctions.

2 Check to see that the battery is fully-charged, as the control unit and sensors depend on an accurate supply voltage in order to properly meter the fuel.

3 Check the air filter element - a dirty or partially-blocked filter will severely impede performance and economy (see Chapter 1).

4 If a blown fuse is found, renew it and see if it blows again. If it does, search for a earthed wire in the harness related to the system.

5 Check the air intake duct from the air cleaner housing to the intake manifold for leaks, which will result in an excessively lean mixture. Also check the condition of the vacuum hoses connected to the intake manifold.

6 Remove the air intake duct from the throttle body and check for carbon and residue build-up. If it's dirty, clean it with aerosol carburettor cleaner (make sure the can says it's safe for use with oxygen sensors and catalytic converters) and a toothbrush (see illustration).

7 With the engine running, place a stethoscope against each injector, one at a time, and listen for a clicking sound, indicating operation (see

    - depressurisation 1 Before servicing any fuel system component, you must relieve the fuel pressure to minimise the risk of fire or personal injury. 2 Remove the fuel filler cap - this will relieve any pressure built-up in the tank. 3 Remove the rear seat from the passenger cabin, then prise up the fuel pump/sender unit access cover (see illustration 3.4). 4 Remove the fuel pump connector (see illustration 3.5a). 5 Start the engine and wait for the engine to stall, then...
