Fuel Pressure Release: Service and Repair
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.
1. Place transmission gear shift lever in "Neutral" (Shift selector lever to "P" range for A/T model), set parking brake, and block drive wheels.
2. Remove relay box cover.
3. Disconnect fuel pump relay from relay box.
4. Remove fuel filler cap to release fuel vapor pressure in fuel tank and then reinstall it.
5. Start engine and run it until it stops for lack of fuel. Repeat cranking engine 2-3 times for about 3 seconds each time to dissipate fuel pressure in
lines. Fuel connections are now safe for servicing.
6. Upon completion of servicing, connect fuel pump relay to relay box and install relay box cover.
FUEL LEAKAGE CHECK PROCEDURE
After performing any service on fuel system, check to make sure that there are no fuel leakages as follows.
1. Turn ON ignition switch for 3 seconds (to operate fuel pump) and then turn it OFF. Repeat this (ON and OFF) 3 or 4 times and apply fuel pressure
to fuel line (until fuel pressure is felt by hand placed on fuel return hose.)
2. In this state, check to see that there are no fuel leakages from any part of fuel system.
