FUEL DELIVERY TESTS
Refer to Relieving Fuel System Pressure on
p. 143.
Check the Evinrude Diagnostics software Stored
Faults screen for current service codes before
troubleshooting. Correct any problems and clear
the codes FIRST.
Inspect all fuel hoses, filters, and connections.
Check quality of fuel supply.
Fuel Pump Static Test
Use the Evinrude Diagnostics software Fuel Pump
test to activate the electric fuel pump. If the pump
runs, the
EMM and fuel pump circuit are not at
fault.
If the pump does not run:
•
The EMM controls power to the fuel pump (pur-
ple/black wire). Check voltage at pin 1 of fuel
pump connector. Voltage should be 12 V when
KEY is first ON, when fuel pump test activated,
or when outboard is cranking or running.
•
Use an ohmmeter to check continuity between
pin 2 of fuel pump connector and ground.
•
Refer to Circulation Pump Resistance Test on
p. 141.
If the pump runs:
•
Refer to Fuel System Pressure Test on p. 139.
•
Refer to Running Fuel System Tests on p. 86.
Fuel Injector Static Test
Use the Evinrude Diagnostics software Fuel Injec-
tor Static Test to activate each fuel injector. Listen
for an audible click from each injector when it is
actuated. If the injector activates, the
EMM and
injector circuits are not at fault.
IMPORTANT:
This test is operating the injectors
with 30 V on the system voltage (55 V) circuit. The
start assist circuit (SAC) of the
EMM converts bat-
tery voltage (12 V) to 30 V of system voltage. Bat-
tery must be fully charged and connections must
be clean and tight. Injector activation should be
carefully confirmed.
WARNING
Protect against hazardous fuel spray.
Before starting any fuel system service,
carefully relieve fuel system pressure.
