ELECTRONIC FUEL INJECTION

Fuel Pump / Fuel Tank Installation

1.

Reinstall the fuel tank assembly through the right side.

2.

Connect the fuel line to the fuel pump outlet and connect
the fuel pump electrical harness.

3.

Reinstall the vent line to the tank fitting.

4.

Install the (2) fuel tank mounting screws and tighten
securely.

5.

Install the (4) screws into the bottom portion of the right-
hand footwell.

6.

Install the front cab assembly (see Chapter 9 “Front Cab”).

7.

Remove the shop towel from the fuel tank inlet, reconnect
the fuel fill hose and tighten hose clamp securely.

8.

Install the front rack assembly (see Chapter 9 “Front
Rack”).

9.

Install the front mud guards (see Chapter 9 “Mud Guards”).

10. Reconnect the negative cable to the battery.

11. Install the upper side panels and seat (see Chapter 9 “Seat

and Side Panels”).

12. Test the fuel pump by turning on the key and listening for

the pump to activate.

FUEL PRESSURE REGULATOR

Operation Overview

The fuel pressure regulator maintains the required operating
system pressure of 43 psi ± 3 psi.  A rubber-fiber diaphragm
divides the regulator into two separate sections, the fuel
chamber and the pressure regulating chamber. The pressure
regulating spring presses against the valve holder (part of the
diaphragm), pressing the valve against the valve seat. The
combination of atmospheric pressure and regulating spring
tension equals the desired operating pressure. Any time the fuel
pressure against the bottom of the diaphragm exceeds the
desired (top) pressure, the valve opens, relieving the excess
pressure, returning the excess fuel back to the tank.

Fuel Pressure Regulator Test

 Refer to the “Fuel Pump Test”  procedure.

Fuel Pressure Regulator Replacement

The regulator is a sealed, non-serviceable assembly. If it is
faulty, the fuel tank assembly must be replaced.  Refer to the
“Fuel Pump / Tank Assembly Replacement” procedure.

FUEL INJECTORS

Operation Overview

The fuel injectors mount into the Integrated Air Fuel Manifold
(IAFM), and the fuel rail attaches to the top end of them.
Replaceable O-rings on both ends of the injector prevent
external fuel leaks and also insulate it from heat and vibration.

When the key switch is on, the fuel rail is pressurized, and the
EFI relay provides voltage to the injectors. During engine
operation, the ECU completes the ground circuit, energizing the
injectors. The valve needle in the injector is opened
electromagnetically, and the pressure in the fuel rail forces fuel
down through the inside. The “director plate” at the tip of the
injector contains a series of calibrated openings which directs
the fuel into the intake port in a cone-shaped spray pattern.

The amount of fuel injected is controlled by the ECU and
determined by the length of time the valve needle is held open,
also referred to as the “injection duration” or “pulse width”. It
may vary in length depending on the speed and load
requirements of the engine.

Fuel Injector Service

Injector problems typically fall into three general categories-
electrical, dirty / clogged, or leakage. An electrical problem
usually causes one or both of the injectors to stop functioning.
Several methods may be used to check if the injectors are
operating.

NOTE: Do not apply voltage directly to the fuel
injectors. Excessive voltage will burn out the
injectors. Do not ground the injectors with the
ignition on. The injectors will open if the EFI relay is
energized.

If an injector is not operating, it can indicate either a bad injector,
or a wiring/electrical connection problem. Check as follows:
