Fuel System Pressure Test; Test Conclusion - Can-Am Renegade 570 2016 Service Manual

NOTE: For access to the fuel tank vent system,
FUEL PUMP ACCESS
refer to

FUEL SYSTEM PRESSURE TEST

The pressure test will show the available pressure
in the system. It validates the pressure regulator
and the fuel pump, and allows for checking the
fuel system for leaks (high pressure side).
FUEL SYSTEM DIAGNOSTIC
NOTE: Refer to the
FLOW CHART in this subsection to help diagnose
a fuel system related problem.
1. Ensure the fuel level in the tank is sufficient.
2. Ensure the battery voltage is over 12 volts.
3. Remove seat.
4. Remove RH side body panel, refer to
subsection.
5. Disconnect the fuel pressure hose from the fuel
injector fuel rail. Refer to
FUEL PRESSURE HOSE
OETIKER CLAMPS
.
6. Remove the 2 most forward locking ties secur-
ing the fuel hose to the upper cable support.
NOTE: This is required to provide more hose
length for proper connection to test equipment.

TYPICAL
1. Forward injector rail fitting
2. Locking ties
7. Install the fuel pressure gauge and fuel hose
adapter between the disconnected injector
hose and fuel rail (in-line installation).

TYPICAL - PRESSURE GAUGE SETUP
1. Pressure gauge to fuel hose adapter
2. Fuel hose adapter to fuel rail
3. Fuel hose adapter to fuel pump pressure hose
8. Reinstall the fuel pump relay (R4) in the forward
fuse box.
9. Turn ignition key ON and observe fuel pressure.
FUEL PRESSURE
(Valid at 12v ± 0.1v)
10. Start engine and observe fuel pressure.
11. Stop engine.
12. Remove test equipment and reconnect fuel
hose to injector fuel rail by proceeding in the
same manner as for its installation.

Test Conclusion

The fuel pressure should be within specification in
static or dynamic tests.
Rapid Pressure Drop
If there is a rapid pressure drop after the engine is
stopped, check for leakage at:
– A fuel hose
– A fuel rail.
NOTE: The fuel pump check valve integral to the
fuel pump module may also be at fault.
If no leak is detected, replace fuel pump.
