CAUTION:
This work must not be done when engine is hot. If done so, it may cause adverse effect to catalyst.
After making sure that engine is cold, relief fuel pressure as follows.
- Place transmission gear shift lever in "Neutral" (shift selector lever to "P" range for A/T vehicle), set parking brake, and block drive wheels.
- Remove fuel pump relay (1) from relay box (2).
- Remove fuel filler cap to release fuel vapor pressure in fuel tank and then reinstall it.
- Start and run engine till it stops for lack of fuel. Crank engine for about 3 seconds, and repeat this a few times to dissipate fuel pressure in lines. Fuel connections are now safe for servicing.
- Upon completion of servicing, install fuel pump relay to relay box (2).
