a. If battery voltage is read, check continuity of
circuit B-29 going towards ECM. If it is good,
try a new ECM.
b. If battery voltage is not read, check continuity
of circuit 7-C going towards VCM. If it is good,
try a new VCM.
Fuel Pump Pressure Test
Before proceeding to the pressure test ensure the
battery is fully charged. Battery voltage must be
over 12 volts.
The pressure test will show the available pressure
at the fuel pump outlet. It validates the pressure
regulator, the fuel pump and leaks in the system.
Open the front storage compartment cover (GTI
RFI Series) or remove the engine cover (3D Se-
ries).
Remove storage basket.
On GTI RFI Series, remove glove box to have ac-
cess to fuel pump. Refer to HULL/BODY section.
Remove air vent tube from front storage area.
Ensure there is no leak from hoses and fittings.
Repair any leak.
Ensure there is enough gas in fuel tank.
Disconnect outlet hose from fuel pump.

Subsection 02 (FUEL TANK AND FUEL PUMP)
The fuel hose may be under pressure. Cov-
er the fuel line connection with an absorbent
shop rag. Slowly disconnect the fuel hose
to release the pressure. Wipe off any fuel
spillage inside bilge.
Install fuel pressure gauge (P/N 529 035 591) be-
tween disconnected hose (in-line installation).
FUEL PRESSURE GAUGE
TYPICAL
1. Hose disconnected from fuel pump
2. In-line installation of fuel pressure gauge
Install safety lanyard and observe fuel pressure.
Do not crank engine. Repeat twice.
