CROSSMEMBER
DESCRIPTION - FRONT CRADLE
CROSSMEMBER
This vehicle uses a one piece cast aluminum cradle
for the front cradle crossmember. The cradle cross-
member is used as the attaching points for the lower
control arms, stabilizer bar and steering gear. The
cradle also has the power steering hoses and the
chassis brake tubes attached to it.
WARNING: If a threaded hole in the suspension cra-
dle needs to be repaired, only use the type of
thread insert and installation procedure specified
for this application.
The threaded holes in the front cradle crossmem-
ber that are used for attachment of the lower control
arm rear bushing retainer, power steering hose and
chassis brake tubes can be repaired. The repair is
done by the installation of a Heli-Coiltthread insert
which has been specifically developed for this appli-
cation. Refer to the Mopar Parts Catalog for the spec-
ified Heli-Coiltthread insert to be used for this
application. The procedure for installing the Heli-
Coiltthread insert is detailed in the Service Proce-
dures section in this group of the service manual.
DESCRIPTION - FRONT CRADLE
CROSSMEMBER THREAD REPAIR
WARNING: When performing this procedure use
only the thread inserts which are specified in the
Mopar Parts Catalog for this repair procedure.
These thread inserts have been specifically devel-
oped for this application and use of other types of
thread inserts can result in an inferior long term
repair.
The threaded holes in the front cradle crossmem-
ber, if damaged, can repaired by installing a Heli-
Coiltthread insert.The threaded holes that are repairable using the
thread insert, are the lower control arm rear bushing
retainer mounting bolt holes, routing bracket attach-
ing locations for the power steering hoses, and brake
hose attachment holes.
This repair procedure now allows the threaded
holes in the cradle crossmember to be repaired, elim-
inating the need to replace the cradle crossmember if
damage occurs to one of the threaded holes.
The thread inserts for this application are specified
by part number in the Mopar Parts Catalog.Do not
use a substitute thread insert.
The specific tools and equipment required to install
the thread insert are listed below. Refer to the
instructions included with the thread insert for the
detailed procedure used for the installation of the
thread insert.
NOTE: The thread inserts for this application are for
the repair of M8x1.25 and M10x1.5 threads. Be sure
the correct tools are used for the required thread
insert size.

FUEL DELIVERY
DESCRIPTION
The front wheel drive car uses a plastic fuel tank
located rear center of the vehicle.
The Fuel Delivery System consists of: the following
items:²Electric fuel pump module
²Fuel filter
²Tubes/lines/hoses
²Fuel injectors
The in-tank fuel pump module contains the fuel
pump. The pump is serviced as part of the fuel pump
module. Refer to Fuel Pump Module.
RSFUEL SYSTEM14-1
ProCarManuals.com

The fuel filter is replaceable, it is mounted on the
outside and on top of the fuel tank. Refer to the
Maintenance Schedules in the Introduction section of
this manual for recommended fuel filter replacement
intervals.
FFV REPLACEMENT PARTS
Many components in a Flexible Fuel Vehicle (FFV)
are designed to be compatible with ethanol. Always
be sure that the vehicle is serviced with correct etha-
nol compatible parts.
CAUTION: Replacing fuel system components with
non-ethanol compatible components can damage
your vehicle and may void the warranty.
OPERATION
The fuel system is provided fuel pressure by an in-
tank pump module. The PCM controls the operation
of the fuel system by providing battery voltage to the
fuel pump through the fuel pump relay. The PCM
requires only three inputs and a good ground to oper-
ate the fuel pump relay. The three inputs are:
²Ignition voltage
²Crankshaft Position (CKP) sensor
²Camshaft Position (CMP) sensor
DIAGNOSIS AND TESTING - FUEL DELIVERY
SYSTEM
(Refer to Appropriate Diagnositic Information)
STANDARD PROCEDURE - FUEL SYSTEM
PRESSURE RELEASE PROCEDURE
(1) Remove Fuel Pump relay from Power Distribu-
tion Center (PDC). For location of relay, refer to label
on underside of PDC cover.(2) Start and run engine until it stalls.
(3) Attempt restarting engine until it will no
longer run.
(4) Turn ignition key to OFF position.
(5) Place a rag or towel below fuel line quick-con-
nect fitting at fuel rail.
(6) Return fuel pump relay to PDC.
(7) One or more Diagnostic Trouble Codes (DTC's)
may have been stored in PCM memory due to fuel
pump relay removal. The DRB IIItscan tool must be
used to erase a DTC.
STANDARD PROCEDURE - DRAINING FUEL
TANK
(1) Release fuel system pressure, refer to the Fuel
System Release Procedure in this section.
(2) Insert a 1/4 inch siphon (max. O. D. 5/16) hose
from a portable fuel siphoning tank through the fuel
filler neck opening into the fuel tank. Hose most
have a 30 degree angle cut on the end to bypass the
check valve in the end of the filler neck. Refer to the
siphoning tank's Manufacturing Instructions.
(3) Drain fuel from fuel tank into siphoning tank.

FUEL LEVEL SENDING UNIT /
SENSOR
DESCRIPTION
The fuel gauge level sending unit is attached to the
side of fuel pump module. The level sensor is a vari-
able resistor.
OPERATION
Its resistance changes with the amount of fuel in
the tank. The float arm attached to the sensor moves
as the fuel level changes.
The fuel level input is used as an input for OBD II.
If the fuel level is below 15% of total tank capacity
several monitors are disabled. There are diagnostics
for the level circuit open and shorted.
REMOVAL
Remove fuel pump module. Refer to Fuel Pump
Module in this section.
(1) Depress retaining tab and remove the fuel
pump/level sensor connector from theBOTTOMof
the fuel pump module electrical connector (Fig. 2).
NOTE: The pump module harness on TOP of flange
is not serviceable or removable.
