SYSTEM ANALYSIS
FUEL DELIVERY TESTS
FUEL DELIVERY TESTS
Refer to Relieving Fuel System Pressure on
p. 146.
Check the Evinrude Diagnostics software
Occurred 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.
IMPORTANT: Do NOT perform static tests using
Diagnostic Power Supply Tool, P/N 587005, with
internal 9 volt batteries only. This will produce
false results. Refer to Communication on p. 67.
If the pump does not run:
• Check voltage at pin 1 of fuel pump connector.
Voltage should be slightly less than 12 V with
KEY ON, or when fuel pump test is activated.
Voltage should be 55 V when the outboard is
cranking or running.
• The EMM controls the fuel pump ground (brown
wire). Use an ohmmeter to check continuity
between pin 2 of fuel pump connector and
ground. Use the fuel pump static test to activate
the control function of the EMM. Resistance
should drop as EMM connects the control circuit
to ground.
• Refer to Circulation Pump Resistance Test on
p. 143.
If the pump runs:
•
Refer to
Fuel System Pressure Test
on p. 141.
•
Refer to
Running Fuel System Tests
on p. 89.
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: Do NOT perform static tests using
Diagnostic Power Supply Tool, P/N 587005, with
internal 9 volt batteries only. This will produce
false results. Refer to Communication on p. 67.
IMPORTANT: This test is operating the injectors
with 12 V battery power on the system voltage
(55 V) circuit. Battery must be fully charged and
connections must be clean and tight. Injector acti-
vation should be carefully confirmed.
A WARNING
Protect against hazardous fuel spray.
Before starting any fuel system service,
carefully relieve fuel system pressure.
