Fuel Injector Resistance Test

Disconnect the battery cables at the battery.
Use a digital multimeter to measure the injector
coil resistance.
Fuel Injector Coil Resistance
2 to 3 

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.

1. Fuel pressure gauge
2. Test fitting
Prime the fuel system and check for leaks. START
outboard and run at idle speed. Hold gauge level
005437
with inlet fitting and monitor gauge for pressure
reading.
Pressure should stabilize and gauge must not
indicate less than 3 psi (21 kPa).
