FUEL SYSTEM PRESSURE RELEASE
| CAUTION | DO NOT perform this procedure when engine is hot. Doing so may have an adverse effect on catalytic convertor. |
- Place transmission in Neutral (M/T) or Park (A/T). Set parking brake and block drive wheels. Disconnect fuel pump relay. See the «FUEL PUMP RELAY LOCATION»(ref-26309-S17469435122001010500000) table.
- Remove fuel filler cap to release fuel vapor pressure in fuel tank. Reinstall fuel filler cap. Start engine and run until engine dies. After engine dies, crank engine 2-3 times for about 3 seconds to dissipate fuel pressure in lines. To restore normal operation, reinstall fuel pump relay.
