Chapter 3 Fuel SystemSection 1 Check Fuel System PressureOn-board inspection
1. Check the operation of the fuel pump.
(1) Connect the positive and the negative of the battery to
appropriate connector sockets of the fuel pump (see Figure 3-1).
Attention: Do not start the engine.
If there is pressure present, you will hear that the fuel is flowing.
If there is no pressure present, check the fusible cutout, fuse, EFI
open-circuit relay, fuel pump, ECM (Electronic Control Module) and
circuit joint.
(2) Turn the ignition switch to "OFF".
2. Check the pressure of the fuel.
(1) Check whether the battery voltage is more than 12V.
(2) Disconnect the negative wiring cable from the battery.
(3) Mount a pressure gauge on the fuel input pipe
(see Figure 3-2).
(4) Connect the negative terminal of the battery.
(5) Measure the fuel pressure.
Fuel oil pressure: 265-304kPa
If the pressure is low, check the fuel pipe and connection,
fuel pump, and fuel filter. If the pressure is too high,
replace the regulator.
(6) Start the engine. Measure the fuel pressure at idle speed. The
fuel pressure is 265-304KPa. If the pressure is unsatisfactory, checkFigure 3-1
Figure 3-3 Figure 3-2Fuel SystemCheck Fuel System Pressure3-15the fuel pump, pressure regulator, and injector, and replace if necessary.
(7) After shutting down the engine, check the fuel pressure and
keep the specified pressure for about 5 minutes. The fuel pressure is:
147KPa.
3. The fuel oil pressure regulator (DR) (see Figure 3-3).
Mounting position: On the distributing pipe for fuel.
Faults: Too low or too high fuel pressure, or hard to start.
General causes: Using poor fuel for a long time results in: 1.
strainer blocked; 2. serious leakage caused by particles and impurities.
Other reasons: Man-made mechanical damage, etc.
Maintenance precautions: During maintenance: 1. Never impact the diaphragm element with high pressure
gas; 2. Never clean it with aggressively corrosive liquid; 3. No distortion caused by external force.
Easy measuring method: For the system with oil return, connect a pressure gauge for the fuel on the suction
pipe, start the engine, and run at idle speed. Now, the fuel pressure in the engine should be about 260KPa; pull out
the vacuum pipe of the fuel pressure regulator, and the pressure should be 300KPa approximately.Battery

2. Remove 3 bolts of the flexibility plate (engine side)
3. Remove starter and 2 cooling hoses.
4. Disconnect neutral switch connector and odometer sensor.
5. Loosen the drain screw under the housing to bleed ATF and tighten the drain screw with sealing glue when
assembling. Tightening torque is 29~35N.m
6. Loosen the locking bolt for select lever cable.
7. Remove Drive Shaft LH&RH, using plastic stopper in the oil sealing of differential.
8. Detach suspension bolts.
9. Separate transmission from engine after bolts between engine and transmission remove.II. Automatic Transmission Installation1. Check whether torque converter of the transmission is in the right position, the methods as follows:
Check whether the distance from 3 anchor point of torque converter to front contact face of the transmission
box A 28mm , If the space A<28 mm, try install again. The way to install is that left hand catch hold of the
central anchor column of the converter and make it in alignment with input shaft as near as possible, push the torque
converter in rotating way by right hand until it gets to the bottom to meet the requirement of A 28 mm. (See
figure 7-1 and 2)
2. Install Flexibility plate and central plate on the crankshaft end face with 6 bolts in the direction of Figure 2.
Tightening torque is 45~55 N.m. Turn the longer hole of the Flexibility plate to the lowest of the engine position
in order to connect torque converter.Section 2 Hydraulic Torque Converter and TransaxleAutomatic Transaxle Assembly Hydraulic Torque Converter and Transaxle3-30 -
