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 multi-tester, measure the current consumption by
connecting the terminal No.1 and No.3 of pump.
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 1Liter.
3. Turn the ignition switch to "ON" position.
4. Connect the terminal No.33 and No.5 of ECU with a service
wire.
5. Measure the fuel delivery from the fuel pump.

TORQUE CONVERTER
The torque converter (refer figure 4.2) consists of a turbine,
stator pump, impeller and a lock-up damper and piston
assembly. As in conventional torque converters, the impeller is
attached to the converter cover, the turbine is splined to the
input shaft and the stator is mounted on the pump housing via
a one way clutch (sprag).
The addition of the damper and piston assembly enables the
torque converter to ‘lock-up’ under favourable conditions. Lock-
up is only permitted to occur in third and fourth gears under
specified throttle and road speed conditions.
Lock-up is achieved by applying hydraulic pressure to the
damper and piston assembly which couples the turbine to the
converter cover, locking-up the converter and eliminating
unwanted slippage. Whenever lock-up occurs, improved fuel
consumption is achieved. Torsional damper springs are
provided in the damper and piston assembly to absorb any
engine torque fluctuations during lock-up.
