Capacitor Testing

1.

Charge the capacitor for 10 seconds using a 12 volt battery
by connecting the positive (+) lead to the Red/White wire
and the negative (-) lead to the brown wire.

2.

Monitor the capacitor voltage with a multimeter. The
voltage should slowly drain down from the initial charge.
If the cap does not hold a charge or drains rapidly, replace
the component.

Fuel Injectors

Fuel injectors are flow tested and then color coded (RED,
BLUE, or YELLOW) based on how much fuel the injector flows
during the test.

800 CFI fuel injectors (all colors) are a high flow version of the
fuel injectors used on 600 / 700 CFI engines.

When replacing a faulty fuel injector, always verify the part
number of the injector for the engine application and use the
same color code. If replacing an injector with a different color
code, all four fuel injectors must be replaced with the new color
so all four injectors are the same color.

After replacing all four injectors, the ECU must be re-flashed so
the fuel calibration map matches the new color coded fuel
injectors.

CAUTION

800 CFI ENGINES USE HIGH FLOW FUEL 

INJECTORS. ALWAYS CHECK THE INJECTOR PART 

NUMBER TO VERIFY ENGINE APPLICATION 

REGARDLESS OF COLOR CODE.

NEVER RUN THE ENGINE WITH DIFFERENT 

COLOR-CODED FUEL INJECTORS. SEVERE 

ENGINE DAMAGE WILL OCCUR.

ALWAYS VERIFY THE ECU CALIBRATION FILE 

MATCHES THE FUEL INJECTOR COLOR CODES.

Fuel Rail Bleeding / Pressure Testing

All CFI engine fuel return hoses feature an inline Schrader valve
that can be used to bleed the fuel system pressure and observe
running system pressure using a fuel pressure gauge.

The model year and engine model will determine which fuel
pressure tool adaptor is required to complete both tasks.

1.

Select the appropriate adaptor.

2.

Connect the adaptor to the fuel return hose Schrader valve.

3.

Connect the adaptor to the fuel pressure / bleed tool gauge.

4.

To observe running fuel system pressure, start the engine
and compare reading to the specification.

5.

To bleed the fuel system pressure after the engine is
stopped, place the tool’s bleed hose into an appropriate fuel-
handling container. Open the valve to release the pressure
and residual fuel.

6.

Close the valve, then remove the gauge and adaptor from
the fuel hose Schrader valve. Replace the Schrader valve
dust cap.

Disconnect Fittings

The fuel hoses on CFI engines feature disconnect fittings that
require special tools to remove. 

The fuel line disconnect tool kit, PS-47152, supplies one 5/16

″

and one 3/8

″

 quick disconnect tool.  These tools are also

commercially available at local auto parts stores.

1.

To disconnect a fuel hose from the fuel pump, or fuel rail,
insert the tapered end of either the 5/16

″

 or 3/8

″

 tool into

the female housing.

2.

Firmly press the tool into the housing while carefully
pulling the male hose outwards.

3.

Reconnect the fuel hoses by coating each hose end with a
light film of two stroke engine oil.

4.

Carefully install the male end of the hose into the center of
the female housing. Firmly push the hoses together until the
male nozzle fully seats behind the spring tabs.

5.

Grasp both hoses and gently pull to verify positive
engagement.
