41Chapter 4 Fuel System
(MR7131A, MR7151A, MR7161A)Section 1 Check Fuel System Pressure1. Remove the fuel tank from the vehicle
2. Check the fuel pump running
(a) Connect the positive and negative battery terminal to the concerned
fuel pump connector. See (Figure 91).
Notice: Do not start engine
The sound of fuel flowing can be heard if there is pressure.
Check fusible link, fuse, EFI open circuit relay, fuel pump, ECU and
wire connector if there is no pressure.
(b) Turn the ignition switch to "OFF" position.
3. Check fuel pressure
(a) Check battery electrical pressure to be above 12V.
(b) Detach negative terminal cable from the battery.
(c) Install pressure gage from the fuel delivery pipe. See (Figure 92).
(d) Connect battery negative terminal.
(e) Measure fuel pressure
Fuel pressure:
304-343kPa
Check fuel pipe & union, fuel pump, fuel filter if the pressure is too
low.
(f) Start engine. Measure fuel pressure at idle. Fuel pressure: 304-343kPa
(g) Check fuel pressure and retain the pressure for approximately 5min after the engine stopped.
Fuel pressure: 147kPaFigure 91Figure 92
