Fuel Pressure Release: Service and Repair
Fuel Pressure Relief Procedure
FUEL PRESSURE RELIEF PROCEDURE
CAUTION: Remove the fuel tank cap and relieve the fuel system pressure before servicing the fuel system in order to reduce the risk of
personal injury. After you relieve the fuel system pressure, a small amount of fuel may be released when servicing the fuel lines, the fuel
injection pump, or the connections. In order to reduce the risk of personal injury, cover the fuel system components with a shop towel before
disconnection. This will catch any fuel that may leak out. Place the towel in an approved container when the disconnection is complete.
NOTE: Do not perform this procedure if the engine is hot. Unburned fuel entering the catalytic converter could damage the converter catalyst.
1. Loosen the fuel filler cap in order to relieve the fuel tank pressure.
2. Remove the instrument panel (IP) storage compartment.
3. Reach in through the IP storage compartment opening and remove the circuit opening relay (1) from the fuse block IP (2).
4. Crank the engine and allow the engine to stall.
5. Crank the engine for an additional 3 seconds in order to assure relief of any remaining fuel pressure.
CAUTION: Refer to Battery Disconnect Caution in Service Precautions.
6. Disconnect the negative battery cable in order to avoid re-pressurizing the fuel system.
7. Install the circuit opening relay (1) into the fuse block IP (2).
8. Install the IP storage compartment.
