Vapor Separator Vent Check; Fuel Injector Pressure Test; Fuel Injector Resistance Test - BRP Evinrude E-TEC Series Service Manual

Vapor Separator Vent Check

Monitor the vapor separator vent hose. No fuel or
a trace of fuel is acceptable. Excessive fuel dis-
charge indicates a vapor separator vent malfunc-
tion. Monitor vent for presence of fuel during
testing. Temporarily install clear tubing for moni-
toring. Replace vapor separator if the venting of
fuel is continuous.

Fuel Injector Pressure Test

Disconnect the battery cables at the battery.
Remove vapor separator assembly. Refer to
Vapor Separator Removal on p. 132.
IMPORTANT:
Perform
mounted to cylinder head.
Seal injector outlet fitting with a cap, such as Plug,
P/N 315391, and a tie strap.
Connect a 0 to 30 psi (0 to 207 kPa) pressure
tester to the inlet fitting. Secure with tie strap.
Pressurize the injector to 30 psi (207 kPa). Pres-
sure must hold for at least five minutes.

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 

@ 72°F (22°C)
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 or green).
Resistance should be the same as, or slightly
higher than, the injector alone.
