FUEL PUMP CIRCUITPFP:17042
DescriptionEBS00KM1
SYSTEM DESCRIPTION
*: The ECM determines the start signal status by the signals of engine speed and battery voltage.
The ECM activates the fuel pump for several seconds after the ignition switch is turned on to improve engine
startability. If the ECM receives a engine speed signal from the crankshaft position sensor (POS) and cam-
shaft position sensor (PHASE), it knows that the engine is rotating, and causes the pump to operate. If the
engine speed signal is not received when the ignition switch is ON, the engine stalls. The ECM stops pump
operation and prevents battery discharging, thereby improving safety. The ECM does not directly drive the fuel
pump. It controls the ON/OFF fuel pump relay, which in turn controls the fuel pump.
COMPONENT DESCRIPTION
A turbine type design fuel pump is used in the fuel tank.

Diagnostic ProcedureNJEC0699
1 CHECK ELECTRONIC CONTROL FUEL INJECTION PUMP POWER SUPPLY CIRCUIT
1. Turn ignition switch “OFF”.
2. Disconnect electronic control fuel injection pump harness connector.
SEF390Y
3. Turn ignition switch “ON”.
4. Check voltage between electronic control fuel injection pump terminal7 and ground.
YEC058A
OK or NG
OK GO TO 3.
NG GO TO 2.
2 DETECT MALFUNCTIONING PART
Check the following.
Harness connectors E75, F36
Harness for open or short between electronic control fuel injection pump and ECM
Harness for open or short between electronic control fuel injection pump and ECM relay
Repair open circuit or short to ground or short to power in harness or connectors.
3 CHECK ELECTRONIC CONTROL FUEL INJECTION PUMP GROUND CIRCUIT FOR OPEN ANDSHORT
1. Turn ignition switch “OFF”.
2. Check harness continuity between electronic control fuel injection pump terminal 6 and ground. Refer to Wiring Dia-
gram.
Continuity should exist.
3. Also check harness for short to power.
OK or NG
OK GO TO 4.
NG Repair open circuit or short to power in harness or connectors.

SMT695D
Install synchronizer hub with its three grooves facing the front
side (3rd input gear side).
SMT699D
Install 3rd & 4th coupling sleeve with its chamfered surface
facing the 4th input gear side.
SMT698DB
4. Position bearing replacer to the front side of input shaft front
bearing.
Align grooves of shifting insert and 3rd gear baulk ring. Then,
press it onto 3rd & 4th synchronizer hub assembly using a drift.
5. Install 4th gear C-ring onto input shaft.
SMT700DA
6. Measure the end play of 3rd & 4th synchronizer hub, and
check if it is within allowable specification below.
End play:
0 - 0.06 mm (0 - 0.0024 in)
7. If not within specification, adjust the end play by changing
thickness of 4th input gear C-ring.
4th input gear C-ring:
Refer to SDS, MT-125.
SMT701DB
8. Install 4th gear needle bearing, 4th gear baulk ring, and 5th
gear front C-ring.
9. Install 4th input gear.
