Fuel Pressure Relief Procedure
Description
WARNING!
Fuel in the fuel system remains under high pressure, even when the engine is not running. Before servicing or
disconnecting any of the fuel lines or fuel system components, the fuel system pressure must be relieved to
prevent accidental spraying of fuel. Failure to follow these instructions may result in serious personal injury or
death.
Perform the following procedure to relieve fuel pressure from the fuel system:1. Remove the cover of the front fuse and relay box.
2. Identify and remove the fuel pump relay from the front fuse and relay box.
3. Start and run engine until it stalls.
4. Attempt to restart engine until it will no longer run.
5. Turn the ignition key to the OFF position.
Fuel Pump
Description
The fuel pump assembly contains the fuel pump motor and fuel level sensor.
Operation
The Engine Control Module (ECM) activates the fuel pump relay for several seconds after the ignition switch is
turned ON. When the relay is activated, it provides voltage to the fuel pump. When the ECM receives an engine
speed signal from the Crankshaft Position (CKP) sensor and a signal from the Immobilizer control module, the ECM
will energize the fuel pump relay.
NOTE :
• The electric fuel pump has different flow ratings based on engine requirements
• For service, the part number of the replacement fuel pump must be the equivalent of the original fuel pump
• Do not operate the fuel pump dry, this will damage the fuel pump
• Keep the fuel tank and pipeline clean, and replace the fuel filter if the fuel pump is replaced
Removal & Installation
WARNING!
Release fuel system pressure before servicing fuel system components. Service vehicles in well-ventilated areas
and avoid ignition sources. Never smoke while servicing the vehicle. This may result in personal injury or death.
NOTE :
The following special tool is required to perform the repair procedure:
•CH-20032 - Fuel Pump Remover
1. Release the fuel system pressure (See Fuel Pressure Relief Procedure in Section 04 Fuel Delivery).
2. Disconnect the negative battery cable.
3. Remove the rear seat cushion.
