Failure to relieve fuel pressure before repairs or disassembly can cause serious personal injury and/or property damage. Fuel pressure is maintained within the fuel lines, even if the engine is OFF or has not been run in a period of time. This pressure must be safely relieved before any fuel-bearing line or component is loosened or removed. On vehicles equipped with inflatable restraints or air bag systems, wait at least 90 seconds after disconnecting the battery cable before performing any other work. The back-up power will keep the restraint system energized for a period of time after the battery is disconnected.
- Before servicing the vehicle, refer to the precautions section.
Perform the following:
- Remove the rear seat cushion.
- Remove the rear floor service hole cover.
- Disconnect the fuel pump connector.
- Start and run the engine, until it stalls.
- Turn the ignition key to the LOCK position.
- Disconnect the negative battery cable.
- Connect the fuel pump connector.
- Install the service hole cover and rear seat cushion.
- Place a catch-pan under the joint to be disconnected. A large quantity of fuel may be released when the joint is opened.
- Wear eye or full face protection.
- Place a shop towel over the area and slowly release the joint using a wrench of the correct size.
- Allow the any fuel left in the line to bleed off slowly before fully disconnecting the joint.
- Plug the opened lines.
