CROSSFIRE INJECTION SYSTEM

SYSTEM DESCRIPTION
The Model 400 Electronic Fuel Injection (EFI) system is a computer controlled
system that uses a pair of Throttle Body Injection (TBI) units, which are
mounted on a single manifold cover on t he 5.0L (VIN 7) engine. Since each TBI
feeds the cylinders on the opposite side of the engine, the system has acquired
the name of Crossf ire Injection.
Fuel is supplied, by an electric fuel pum p located in the fuel tank, to the front
TBI fuel accumulator. From the accumulator, it is carried to the rear TBI fuel
pressure regulator by a c onnecting tube. Unused fuel is sent to the fuel tank
through a separate return line.

17. Check the throttle position sensor voltage and adjust if necessary.
18. Perform the Minimum Idle and Thro
ttle Valve Synchronization adjustment
procedures.
INJECTOR REPLACEMENT
The removal and installation procedures fo r the Crossfire injection system's fuel
injector is identical to the Throttle Bo dy Injection (TBI) system. Please refer to
the TBI fuel injector procedures earlier in this repair guide.
ADJUSTMENTS
PRELIMINARY ADJUSTMENTS
The preliminary adjustments are performed if tampering with the idle speed or
synchronization is evident and when either of the throttle bodies or the manifold
cover have been replaced. They must be performed BEFORE the Minimum Idle
and Throttle Valve Synchronizing procedure.
THROTTLE VALVE SYNCHRONIZING
1. Turn BOTH front and rear unit throttle stop screws counterclockwise enough to break contact with the related throttle lever tangs.
2. Adjust the throttle synchronizing scr ew to allow BOTH throttle valves to
close. The throttle rod end bearing w ill move freely on the front unit
throttle lever stud when both valves are closed.
3. Turn the front unit th rottle stop screw clockwise slowly until it makes
contact with the throttle lever tang. Turn the screw clockwise an
additional
1/4 turn.
4. Turn the rear unit throttle stop screw clockwise slowly until it makes
contact with the throttle lever t ang. Turn the screw an additional
1/2 turn.

21. Install the fuel rail assembly.
22. Temporarily connect the negative battery cable. a. With the engine OFF and the igniti on ON, check for fuel leaks.
b. Disconnect the negative battery cable.
23. Install the intake plenum and runners.
24. Connect the negative battery cable.
IDLE AIR CONTROL VALVE
REMOVAL & INSTALLATION 1. Unplug the electrical connector from idle air control valve.
2. Remove the idle air control valve.
To install: 3. Before installing the idle air contro l valve, measure the distance that the
valve is extended. Measurement s hould be made from the motor housing
to the end of the cone. It should not exceed 28.5mm (1
1/8 in.), or damage
to the valve may occur when installed.
4. On 1985-1992 models, identify the replacement IAC valve as being
either Type 1 (with collar at electric terminal end) or Type 2 (without
collar). If measuring distance is great er than specified above, proceed as
follows:
• Type 1: Use finger pressure to slowly retract the pintle.
• Type 2: Compress retaining spring from valve while turning valve
in with a clockwise motion. Return spring to original position with
straight portion of spring end aligned with flat surface of valve.
On IAC valves that have already been in service, do not push or pull on the
valve pintle. The force required to move the pintle may damage the threads on
the worm drive.
5. Use a new gasket or O-ring and install the IAC valve into the throttle body.
6. Allow the ECM to reset the idle air control valve using the procedure
described earlier in this section.

MAINTENANCE OR REPAIR?
Maintenance includes routine inspecti
ons, adjustments, and replacement of
parts which show signs of normal wear . Maintenance compensates for wear or
deterioration. Repair implies that someth ing has broken or is not working. A
need for a repair is often caused by lack of maintenance. for example: draining
and refilling automatic transmission fl uid is maintenance recommended at
specific intervals. Failure to do this can shorten the life of the
transmission/transaxle, requiring very expen sive repairs. While no maintenance
program can prevent items from eventually breaking or wearing out, a general
rule is true: MAINTENANCE IS CHEAPER THAN REPAIR.
Two basic mechanic's rules should be mentioned here. First, whenever the left
side of the vehicle or engine is refe rred to, it means the driver's side.
Conversely, the right side of the vehi cle means the passenger's side. Second,
screws and bolts are removed by turn ing counterclockwise, and tightened by
turning clockwise unless specifically noted.
Safety is always the most important rule. Constantly be aware of the dangers
involved in working on an automobile and take the proper precautions. Please
refer to the information in this se ction regarding SERVICING YOUR VEHICLE
SAFELY and the SAFETY NOTICE on the acknowledgment page.
AVOIDING THE MOST COMMON MISTAKES
Pay attention to the instructions prov ided. There are 3 common mistakes in
mechanical work:
1. Incorrect order of assembly, di sassembly or adjustment. When taking
something apart or putting it toget her, performing steps in the wrong
order usually just costs you ex tra time; however, it CAN break
something. Read the entire proc edure before beginning. Perform
everything in the order in which the instructions say you should, even if
you can't see a reason for it. When you' re taking apart something that is
very intricate, you might want to draw a picture of how it looks when
assembled in order to make sure you get everything back in its proper
position. When making adjustments, per form them in the proper order.
One adjustment possibly will affect another.
2. Overtorquing (or undertorquing). While it is more common for overtorquing to cause damage, undertorquing may allow a fastener to
vibrate loose causing serious dam age. Especially when dealing with
aluminum parts, pay attention to tor que specifications and utilize a torque
wrench in assembly. If a torque figure is not available, remember that if
you are using the right tool to perfo rm the job, you will probably not have
to strain yourself to get a fast ener tight enough. The pitch of most
threads is so slight that the te nsion you put on the wrench will be
multiplied many times in actual fo rce on what you are tightening.
There are many commercial products avai lable for ensuring that fasteners won't
come loose, even if they are not torqued just right (a very common brand is

3. Clean all dirt from
the area around the cover. Re move the bolts retaining
the cover to the housing. Pry the co ver from the differential housing and
allow the fluid to drain into the catch pan.
To install: 4. With the cover and housing washed free of oil and gasket material, apply sealer to the mating surfaces.
5. Using a new gasket, install the cove r and torque the bolts to 20 ft. lbs.
(27 Nm) in a clockwise pattern to in sure uniform draw on the gasket. Fill
the differential with fluid through the fi ll plug and add limited slip additive,
as required.
6. Install the parking brake cable guides, if removed.
7. The fluid level shou ld reached a level within
3/8 in. (10mm) of the filler
plug hole. Replace the filler plug. Low er the car and inspect for leaks.
COOLING SYSTEM

CAUTION - When draining the c oolant, keep in mind that cats and dogs are
attracted by the ethylene gl ycol antifreeze, and are quite likely to drink any that
is left in an uncovered container or in puddles on the ground. This will prove
fatal in sufficient quantity. Always drai n the coolant into a sealable container.
Coolant should be reused unless it is c ontaminated or several years old (in
which case it should be taken to a recycli ng facility such as a service station).
FLUID RECOMMENDATIONS
When adding or changing the fluid in the system, create a 50/50 mixture of high
quality ethylene glycol antifreeze and water.
LEVEL CHECK

Fig. 1: Fluid level marks on the cool ant recovery tank. With a warm system,
coolant level should be just below the FULL HOT mark on tank.

Fig. 5: Periodically remove all debris from the radiator fins
CAUTION - Do not remove a radiator cap wh ile the engine and radiator are still
hot. Danger of burns by scalding fluid and steam under pressure may result!
1. With a cool engine, slowly rotate t he radiator cap counterclockwise to the
detent without pressing down on the cap.
2. Wait until any remaini ng pressure is relieved by listening for a hissing
sound.
3. After all the pressure is relieved, press down on the cap and continue to
rotate the radiator cap counterclockwise.
4. With a suitable container to catc h the fluid under the radiator, open the
radiator drain cock.
5. If equipped, remove the engine blo ck drain plugs and the knock sensor,
located on either side of the engine block. This will help to drain the
coolant from the block.
6. Loosen or slide the recovery tank hos e clamp at the radiator filler neck
overflow tube and remove the hose. Holding the hose down to the drain
pan, allow the recovery tank to empty. Attach the hose to the filler neck
overflow and tighten the clamp.
7. Close the radiator drain cock and install the engine block drain plug and
knock sensor. Tighten the knock sensor to 14 ft. lbs. (19 Nm), the engine
block drain plug to 15 ft. lbs. (21 N m), and the drain cock to 13 inch lbs.
(1.5 Nm).
8. Add enough coolant mixture to fill the system to a level just below the
radiator neck. Fill the reservoir a ssembly to the "FULL COLD" mark.
