Section 07 ENGINE MANAGEMENT (DI)
Subsection 02 (COMPONENT INSPECTION AND ADJUSTMENT)
Electrical Test
When connecting the safety lanyard to the DESS
post, the fuel pump should run for 2 seconds to
build up the pressure in the system.
If the pump does not work, disconnect the con-
nector from the fuel pump.
Install a temporary connector on the fuel pump
with wires long enough to make the connection
outside the bilge and apply voltage (12 V) to this
test harness.
CAUTION: Running pump a few minutes with
reverse polarity can damage the pump.
If pump does not run, replace the fuel pump.
Otherwise, check the continuity of the fuel pump
circuit.
Disconnect the AMP connector number 4 on the
MPEM.
Using a multimeter, check continuity between ter-
minals of circuits 24 and 26.
If wiring harness is good, try a new MPEM. Refer
to MPEM REPLACEMENT procedures elsewhere
in this section.
Otherwise, repair the wiring harness/connectors
between AMP connector and fuel pump.
Fuel Pump Replacement
Ensure fuel pressure has been released in the sys-
tem using the VCK (Vehicle Communication Kit).
Removal

Disconnect inlet and outlet hoses from fuel pump
using tool (P/N 529 035 714).
Remove fuel pump retaining nuts.
NOTE: Hold the studded C-ring while removing
the last fuel pump retaining nut. C-ring may fall

F08R05A
CAUTION: While pulling out the fuel pump, pay
attention to fuel sensor float arm. Float arm
can get stuck and bend which can reduce the
fuel sensor capabilities.
Pull fuel pump out. Wipe off any fuel spillage in
the bilge.
