Fuel Pressure Relief Procedure

CAUTION
!
This work must not be done when engine is
hot. If done so, it may cause adverse effect to
catalyst.
NOTE
If ECM detects DTC(s) after servicing, clear
DTC(s) referring to "DTC Clearance: in
Section 1A".
1) Make sure that engine is cold.
2) Shift transaxle gear shift lever in "Neutral" (shift
select lever in "P" range for A/T model), set parking
brake and block drive wheels.
3) Remove fuse box No.2 cover.
4) Disconnect fuel pump relay (1) from fuse box No.2
(2).
5) Remove fuel filter cap in order to release fuel vapor
pressure in fuel tank, and then reinstall it.
6) Start engine and run it until engine stops for lack of
fuel. Repeat cranking engine 2 – 3 times for about 3
seconds each time in order to dissipate fuel pressure
in lines. Fuel connections are now safe for servicing.
7) After servicing, connect fuel pump relay (1) to fuse
box No.2 and install fuse box No.2 cover.

2) In this state, check to see that there are no fuel
leakages from any part of fuel system.
