Fuel Pump Replacement - Polaris RANGER ETX 2015 Owner's Manual

6. If the pump did not activate (Step 5), disconnect the
harness connector from the fuel pump. Connect a DC
voltmeter across terminals "3" and "4" in the plug on
the vehicle fuel pump harness. Turn on the key switch
and observe voltage to ensure a minimum of 7 volts is
present.
NOTE
If the voltage was below 7 VDC, test the battery, ignition
switch, relay(s), wiring harness and ECU.
7. If the reading is between 7 and 14 volts, turn key
switch off and connect an ohmmeter between
terminals "3" and "4"' at the white fuel pump
connector to check for continuity within the fuel pump.
NOTE
If there was no continuity between the pump terminals,
replace the fuel pump assembly.
8. If voltage at the plug was within the specified range,
and there was continuity across the pump terminals,
reconnect the plug to the fuel pump, making sure you
have a clean connection. Turn on the key switch and
listen for the pump to activate.
NOTE
If the pump starts, repeat steps 3, 4 and 5 to verify
correct pressure.
9. If the pump still does not operate, check for correct
ECU operation by plugging in a known-good ECU of
the same model.
NOTE
If the pump still does not operate, replace the fuel pump
assembly.

FUEL PUMP REPLACEMENT

WARNING
Gasoline is extremely flammable and explosive under
certain conditions.
Always stop the engine and refuel outdoors or in a well
ventilated area.
Do not smoke or allow open flames or sparks in or near
the area where refueling is performed or where
gasoline is stored.
Do not overfill the tank. Do not fill the tank neck.
If you get gasoline in your eyes or if you swallow
gasoline, seek medical attention immediately. Do not
induce vomiting.
If you spill gasoline on your skin or clothing,
immediately wash it off with soap and water and
change clothing.
Never start the engine or let it run in an enclosed area.
Engine exhaust fumes are poisonous and can result
loss of consciousness or death in a short time.
Never drain the fuel when the engine is hot. Severe
burns may result.
Always wear safety goggles when working with high
pressure or flammable fluids. Failure to do so could
result in serious injury or complications.
CAUTION
It is possible for pressurized fuel to be present when
disconnecting the fuel line.
It is recommended to allow the vehicle to sit for a period
of one hour after shutting off the engine before
servicing the fuel pump. This allows the exhaust to cool
and fuel pressure to drop.
1. Remove the seat to access the fuel pump.
2. Disconnect the battery (-) negative cable.
3. Ensure that static has been discharged from you by
touching a ground source such as the engine or
frame.
4. While holding a shop towel over the fuel line
connector, disconnect the quick connect fuel line
from the fuel pump.
NOTE
A small amount of fuel may come out of the fuel line or
tank. Properly drain fuel into a suitable container.
