DescriptionNJEC0781When the gear position is in “Neutral”, neutral position is “ON”. ECM detects the position because the conti-
nuity of the line (the “ON” signal) exists.

MONITOR ITEM CONDITION SPECIFICATION
P/N POSI SW Ignition switch: ONShift lever: Neutral ON
Except above OFF
On models not equipped with park/neutral position (PNP) switch, “OFF” is always displayed regardless of gear shift position.
ECM Terminals and Reference ValueNJEC0783Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM’s transistor. Use a ground other than ECM terminals, such as the ground.

Checking Fuel LinesNJFE0009Inspect fuel lines and tank for improper attachment, leaks, cracks,
damage, loose connections, chafing or deterioration.
If necessary, repair or replace faulty parts.
MMA104A
CAUTION:
Tighten high-pressure rubber hose clamp so that clamp end is
3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.
Removal and InstallationNJFE0004WARNING:
When replacing fuel line parts, be sure to observe the following.
Put a “CAUTION: FLAMMABLE” sign in workshop.
Be sure to furnish workshop with a CO
2fire extinguisher.
Do not smoke while servicing fuel system. Keep open flames and sparks away from work area.
CAUTION:
Before removing fuel line parts, carry out the following procedures:
a) Put drained fuel in an explosion-proof container and put the lid on securely.
b) Release fuel pressure from fuel line. Refer to EC-34, “Fuel Pressure Release”.
c) Disconnect battery ground cable.
Always replace O-ring and clamps with new ones.
Do not kink or twist tubes when they are being installed.
Do not tighten hose clamps excessively to avoid damaging hoses.
After installing tubes, run engine and check for fuel leaks at connections.

7. Disconnect electrical connector.
8. Disconnect the quick connector as follows.
a. Put mating marks on tubes and connectors for correct instal-
lation.
PBIC0709E
b. Hold the connector while pushing in buttons, and pull out the
tube.
CAUTION:
The tube can be removed when the buttons are completely
depressed. Do not twist it more than necessary.
Do not use any tools to remove the quick connector.
Keep the resin tube away from heat. Be especially careful
when welding near the tube.
Prevent acid liquid such as battery electrolyte etc. from
getting on the resin tube.
Do not bend or twist the tube during installation and
removal.
PBIC0713E
To keep clean the connecting portion and to avoid damage
and foreign materials, cover them completely with plastic
bags or something similar.

9. From rear left area of fuel tank, remove filler hose, vent hose,
and VEEP hose.
CAUTION:
To prevent fuel from flowing out, install a blind cap immedi-
ately after the fuel hose is disconnected.

Bleeding Fuel FilterNJFE00231. After the repair, bleed air from the piping by pumping the prim-
ing pump up and down until it becomes heavy.
2. To start the engine, rotate the starter for a maximum of 30
seconds.
To start the engine more quickly, crank the engine while pump-
ing the priming pump (requires two workers).
3. If the engine does not start after rotating the starter for a maxi-
mum of 30 seconds, stop it once, and pump the priming pump
again until it becomes heavy.
4. Rotate the starter again until the engine starts running.
5. After the engine starts, let it idle for at least 1 minute to stabi-
lize the behavior.
NOTE:
When air is bled completely, pumping the priming pump sud-
denly becomes heavy.
Stop the operation at that time.
If it is difficult to bleed air by pumping the priming pump (the
priming pump does not become heavy during pumping), dis-
connect the fuel supply hose between the fuel filter and the
injection pump. Then, pump the priming pump up and down,
and make sure that fuel comes out. (Use a pan and be care-
ful not to spill fuel. Keep fuel clear of the engine.) After that,
connect the hose, then bleed air again.
DEF017
Checking Priming PumpNJFE0024Before checking priming pump, make sure that fuel filter is
filled with fuel.
1. Disconnect fuel return hose.
Place a suitable container beneath hose end.
2. Pump priming pump and check that the fuel overflows from the
hose end. If not, replace priming pump.
Removal and InstallationNJFE0015WARNING:
When replacing fuel line parts, be sure to observe the following.
Put a “CAUTION: FLAMMABLE” sign in workshop.
Be sure to furnish workshop with a CO
2fire extinguisher.
Do not smoke while servicing fuel system. Keep open flames and sparks away from work area.
CAUTION:
