Fuel Pump/Fuel Level Sensor - Arctic Cat PROWLER HDX 2015 Service Manual

Fuel Pump/Fuel Level
Sensor
Component data can be retrieved using the CATT II. Uti-
lize the Sensor Data screen.

NOTE: Preliminary checks may be performed on
this component using the diagnostic mode on the
LCD gauge (see EFI Diagnostic System in the Electri-
cal System section).
The electric fuel pump and fuel level sensor are not ser-
viceable components. If either component fails, it must
be replaced.
TESTING
! WARNING
Whenever any maintenance or inspection is made on
the fuel system during which there may be fuel leakage,
there should be no welding, smoking, open flames, etc.,
in the area.
AT THIS POINT
Prior to removing the electric fuel pump, the following
check should be performed to determine that removal is
necessary.
1. Turn the ignition switch ON and listen for a momen-
tary "whirring" sound of the pump building pressure.
If the sound is heard (10 seconds), no electrical
checks are necessary. Turn the ignition switch OFF.
2. Disconnect the gasline hose from the fuel rail; then
install a suitable pressure gauge.
! WARNING
Gasoline may be under pressure. Place an absorbant
towel under the connector to absorb any gasoline spray
when disconnecting.
3. Turn the ignition switch to the ON position. The fuel
pressure should build until the pump shuts off. Pres-
sure should read 3.0 kg/cm
140
FI092A
2
(43 psi).
4. If the pump is not running, disconnect the fuel pump/
sensor connector by reaching under the rear rack
from behind.
5. Connect a multimeter to the power supply leads with
the red tester lead to the red wire and the black tester
lead to the black wire; then turn the ignition switch to
the ON position. The meter should read battery volt-
age. If battery voltage is indicated and the fuel pump
does not run, replace the pump assembly. If no bat-
tery voltage is indicated, check the ECM and the
vehicle tilt sensor.
REMOVING
1. Remove the key from the ignition switch.
! WARNING
Always ensure that power cannot be inadvertently
applied to the ignition/ECM when working on the fuel
system. If the ignition switch is turned on, the electric
fuel pump will start and gas could be rapidly pumped
and spilled resulting in fire and severe injury.
2. Remove the seat, seat back, and seat base; then dis-
connect the negative battery cable.
3. Disconnect the electrical plug from the main harness;
then disconnect the gasline hose from the fuel pump.
4. Mark the fuel pump mounting and gas tank for
installing purposes; then remove the screws securing
the fuel pump to the gas tank and remove the fuel
pump.
CAUTION
Take care not to damage the float or float arm or
replacement of the entire assembly will be necessary.
5. Using duct tape or other suitable means, cover the
fuel pump opening.
INSPECTING
AT THIS POINT
If the pump has failed earlier test and must be replaced,
proceed to INSTALLING.
1. Inspect the fuel screen and blow clean with low pres-
sure compressed air.
2. Move the float lever and check for free movement.
The float assembly should return to the lower posi-
tion without force. If not, replace the fuel level sen-
sor assembly.
3. Test the fuel level sensor by connecting a multimeter
(A) to the fuel level sensor leads (B); then select
OHMS. The multimeter should show 5 ohms at full
fuel position (C) and 95 ohms at empty fuel position
(D).
