Description
The fuel filter consists of a housing with an integrated filter element.
Operation
The fuel flows through the filter from the outside to the inside. As a result, any impurities are trapped inside the filter.

Fuel Injector
Description
The fuel injectors are positioned in the intake manifold with the nozzle ends directly above the intake valve port.
Operation
Injector operation is controlled by a ground path provided for each injector by the Engine Control Module (ECM).
Injector on-time (pulse-width) is variable, and is determined by the ECM. Based on the engine operating conditions,
the ECM will control injector pulse-width operation to obtain optimum performance.

Description
The fuel pressure regulator is connected to the fuel rail. The fuel pressure regulator has a vacuum connection to it.
The fuel pressure regulator is used to regulate the fuel pressure in the fuel system.
NOTE :
The 2.4L is the ONLY engine that uses an external fuel pressure regulator.
Operation
The fuel pressure regulator is designed to keep the fuel pressure in the fuel system at a constant pressure. It does
this with a spring-loaded diaphragm that controls a valve. The valve, when opened by excessive pressure in the fuel
lines, uncovers a fuel line that returns excess fuel to the fuel tank. The vacuum connection is there to help reduce
emissions during deceleration. During deceleration, the vacuum connection serves to open the fuel return valve
wider, which reduces pressure in the system and prevents excess hydrocarbon emissions due to less fuel being
injected as a result of the lower pressure in the system.

WARNING!

and avoid ignition sources. Never smoke while servicing the vehicle. This may result in personal injury or death.

5. Remove the fuel pressure regulator.
6. Installation is in the reverse order of removal.
Installation Notes:
• Install new seals on the fuel pressure regulator sealing surfaces.
• Coat the surface of the fuel pressure regulator O-ring seal with clean engine oil before assembly.
• While installing the fuel pressure regulator, ensure that the fuel pressure regulator rotates smoothly in the fuel
distribution tube. If it does not rotate smoothly, the O-ring seal may have been damaged. Remove the fuel
pressure regulator and inspect the O-ring seal for damage.
Fuel Pressure Regulator Inspection
1. Connect a fuel pressure gauge to the inlet fuel pipe.
2. Start and idle the engine (note the fuel pressure).
3. Increase the engine speed to 2500 RPM (note the fuel pressure).

The battery, starting and charging systems operate in conjunction with one another, and must be tested as a com-
plete system. For correct operation of starting/charging systems, all components used in these 3 systems must per-
form within specifications. When attempting to diagnose any of these systems, it is important that you keep their
interdependency in mind. These components form two separate circuits, a high amperage circuit that feeds the
starter motor up to 150 amps, and a control circuit that operates on less than 20 amps.
