Use a digital multimeter with appropriate adapter
leads to measure resistance of the complete injec-
tor circuit, including injector and associated wiring.
Measure resistance between pin 1 (white/red) of
injector connector (connected) and the appropri-
ate pin location of
EMM
J1-B connector (discon-
nected). Refer to engine wiring diagram for
specific
EMM
J1-B connector pin location for the
injector circuit being tested (blue, purple or green).
Resistance should be the same as, or slightly
higher than, the injector alone.
Circulation Pump Resistance Test
Disconnect the battery cables at the battery.
Use a digital multimeter with appropriate adapter
leads to measure the fuel pump circuit and coil
resistance.
Lift Pump Pressure Test
Install a 0 to 15 psi (0 to 103 kPa) Fuel Pressure
Gauge, P/N 5006397 or equivalent, to the lower
fuel pressure test fitting.
Prime the fuel system and check for leaks. START
outboard and run at idle speed. Hold gauge level
with inlet fitting and monitor gauge for pressure
reading.
Pressure should stabilize and gauge must not
indicate less than 4 psi (27 kPa).
Results:
Normal pressure

Make sure no air leaks or restrictions exist in
the fuel supply hose or boat fuel system.
Low pressure
•
Check pulse hoses and fittings for restrictions.

Check fuel flow through fuel lift pump. Use fuel
primer bulb to force fuel through pump.

Check fuel flow through fuel lift pump. Use fuel
primer or primer bulb to force fuel through
pump.
•
Momentarily prime or squeeze primer bulb to
check gauge operation.
