FUEL SYSTEM
| WARNING | ALWAYS relieve fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components. |
| CAUTION | When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See the COMPUTER RELEARN PROCEDURES article in the GENERAL INFORMATION section before disconnecting battery. |
FUEL SYSTEM PRESSURE RELEASE
- Turn ignition off. Disconnect negative battery cable. Slowly open fuel tank cap to release pressure in tank. Remove fuel rail pressure test port cap. Place open end of Fuel Pressure Release Hose (C-4799-1) in approved gasoline container. NOTE: Fuel Pressure Gauge (C-4799-A) contains Hose (C-4799-1).
- Connect other end of pressure release hose to test port. As fuel pressure release hose is tightened onto fuel rail pressure test port, fuel pressure will bleed-off into container.
FUEL PUMP
| WARNING | Wear eye protection when servicing fuel system. |
| WARNING | Fuel reservoir of fuel pump does not empty when fuel tank is drained. Fuel may spill when removing fuel pump. |
