Measure the Fuel Delivery from the Fuel Pump

1. Disconnect the return pipe from fuel distributor and insert the appropriate hose into it.

2. Place the hose end into the beaker with the minimum capacity of 1 Liter

3. Turn the ignition switch to “ON” position.

4. Connect the terminal No. 33 and No. 5 of ECM with a service wire.

5. Measure the fuel delivery from the fuel pump

Notice

Check the fuel filter and fuel line when the fuel delivery is not within specified value.

Measure the Current Consumption of Fuel Pump

1. Remove the fuel pump relay from fuse and relay box in trunk, and turn the ignition switch to “ON” position.

2. Using a multimeter, measure the current consumption by connecting the terminal No. 30 and No. 87 of the fuel

pump relay connector.

Notice

Replace the fuel pump relay if the measured value is over 9 A.

Specified value

1 Liter/max. 35 sec.

Specified value

FUEL INJECTOR

The Multipoint Fuel Injection (MFI) assembly is a solenoid-operated device controlled by the Engine Control Module
(ECM) that meters pressurized fuel to an each individual cylinder. The injector sprays the fuel, in precise quantities at
a point in time determined by the ECM, directly to ward the cylinder intake valve. ECM energizes the fuel injector
solenoid to lift the needle valve and to flow the fuel through the orifice. This injector’s discharge orifice is calibrated to
meet the effective fuel atomization necessary for both ensuring the maximum homogeneity in the air-fuel mixture and
holding the condensation along the walls of the intake tract to a minimum.

Fuel enters the top feed injector from above and flows through its vertical axis. The lower end extends into the intake
valve. Fuel from the tip is directed at the intake valve, causing it to become further atomized and vaporized before
entering the combustion chamber.

A fuel injector which is stuck partially open would cause a loss of fuel pressure after the engineis shut down. Also, an
extended crank time would be noticed on some engines. Dieseling could also occur because some fuel could be
delivered to the engine after the ignition is turned off.
