FUEL PUMP PRESSURE TEST
1. Valve on gauge
MODELS
FUEL PRESSURE (
when
pressing the START
button)
1503 4-TEC
supercharged
intercooled
386 - 414 kPa (56 - 60 PSI)
Test when Cranking or Starting Engine
Crank or start engine and observe fuel pressure.
The fuel pressure should be the same as above.
If pressure i
s good, fuel pump and pressure regu-
lator are fun
ctioning correctly.
A rapid pressure drop indicates leakage either
from the fuel rail or from the fuel pump check
valve. Check fuel rail for leaks.
If leak occurs while pressing the START button
and fuel rail is not leaking, then replace fuel pump
module.
Aslowpress
ure drop indicates leakage either
from a fuel i
njector or from the fuel pressure
regulator i
n the fuel pump module. To check
fuel inject
ors for leaks, refer to the
ELECTRONIC
FUEL INJEC
TION (EFI)
subsection. If injectors
are not lea
king, then replace fuel pump.
Release fuel pressure in system using the valve
on the pressure gauge.
Remove pressure gauge and reinstall fuel hose on
fuel pump module.
WARNING
Wipe off any fuel spillage in the bilge. Fuel
is flammable and explosive under certain
conditions. Always work in a well ventilated
area.
Reinstall all removed parts.
