Check the resistance of the fuel injector circuits.
Disconnect the AMP plug connector #4 on the
MPEM.
Using a multimeter, check resistance value be-
tween terminal as follows.
The resistance should be between 2.3
Ω
and
2.5
Ω
at temperature of 20°C (68°F).
If resistance value is incorrect, check wiring har-
ness between AMP plug connector and fuel injec-
tors for damaged wires or bad connections. Repair
if necessary.
Recheck resistance value at AMP plug connector #4.
If not within specification, replace the fuel injector.
Leakage Test (fuel injectors)
To perform a leakage test, the injectors and fuel rail
have to be removed from engine. See REMOVAL
in this subsection for the procedure.
NOTE:
Do not detach injectors from fuel rail.
Reconnect the wire connector of the injector.
Place each injector in a clean bowl.
Install the safety lanyard cap on the switch to ac-
tivate the fuel pump.
Check for fuel leakage from the injector nozzle.
There should be less than 1 drop of fuel per minute.
1. Fuel injectors
2. Fuel rail
3. Injector nozzles
If not within specification, replace the fuel injector(s).
LEAK TEST
(supply and ventilation circuits)
Refer to FUEL SYSTEM.
HIGH PRESSURE TEST
(fuel pump circuit)
Before proceeding to the pressure test ensure the
battery is fully charged. Battery voltage must be
over 12 volts.

WARNING
The fuel hose may be under pressure. Cover
the fuel line connection with an absorbent
shop rag. Slowly disconnect the fuel hose to
release the pressure. Wipe off any fuel spill-
age inside bilge.
