Fuel Pump Control Circuit
CIRCUIT DESCRIPTION
In the diagram below, when the engine is cranked, current flows form terminal ST of the igni\
tion switch to
terminal STA of ECM (STA signal).
When the STA signal and NE signal are input to the ECM, Tr1 is turned ON, current flows to coil of the circuit
opening relay, the relay switches on, power is supplied to the fuel pump and the fuel\
pump operates.
While the NE signal is generated (engine running), the ECM keeps Tr1 ON (circuit opening relay ON) and
the fuel pump also keeps operating.
The fuel pump speed is controlled at 2 levels (high speed or low speed) b\
y the condition of the engine (start-
ing, light load, heavy load). When the engine starts (STA ON), Tr2 in the ECM is OFF, so battery voltage is
applied directry to the fuel pump. Fuel pump operates at high speed.
After the engine starts, during idling or light loads, since Tr2 goes ON, power is supplied to the fuel pump
via the fuel pump resistor.
Fuel pump operates at low speed.

(3) With the engine OFF, add new fluid through the oil
filler pipe.
Fluid type: ATF DEXRON ®II
Capacity:
Dry fill: 11.0 liters (11.6 US qts, 9.7 Imp. qts)
Drain and refill: 1.9 liters (2.0 US qts, 1.7 Imp. qts)
(4) Start the engine and shift the shift lever into all posi-
tions from P to L position and then shift into P posi-
tion.
(5) With the engine idling, check the fluid level. Add fluid up to the COOL level on the dipstick.
(6) Check the fluid level at the normal operating tem- perature 70 − 80° C (158 − 176°F) and add as nec-
essary.
NOTICE:
Do not overfill.
(d) Check the fluid leaks.
Check for leaks in the transmission.
If there are leaks, it is necessary to repair or replace O −rings,
Seal packings, oil seals, plugs or other parts.
(e) Inspect and adjust the throttle cable. (1) Check that the throttle valve is fully closed.
(2) Check that the inner cable is not slack.
(3) Measure the distance between the outer cable endand stopper on the cable.
Standard distance: 0 − 1 mm (0 − 0.04 in.)
If the distance is not standard, adjust the cable by the adjusting
nuts.
(f) Inspect and adjust the shift lever position. When shifting the shift lever from the N position to other
positions, check that the lever can be shifted smoothly
and accurately to each position and that the position indi-
cator correctly indicates the position.
If the indicator is not aligned with the correct position, carry out
the following adjustment procedures. (1) Loosen the nut on the control rod.
(2) Push the control rod fully rearward.
