Workshop Manual

work correctly. No Replace the fuel
injector
Yes Replace fuel 12 Check if fuel is bad or moisture.
No 18
Yes Next step 13 Check if the fuel pressure value is below 400
kPa.
No 17
Yes Next step 14 Close the fuel manometer valve. Re-engage the
ignition switch to let the fuel pump run for a
period of time, and then check if fuel pressure
can be built up.
No 16
Yes Check other part 15 Open the valve of fuel gauge and clamp the oil
return pipe by oil return baffle so that the oil can
not return. Check if the oil pressure occurs
immediately.
No Repair or replace
the fuel pump
Yes Repair or replace
oil intake pipe
16 Check if there is leakage or jam in oil intake
pipe.
No Replace oil pump
Yes Repair or replace
oil return pipe
17 Check if the oil return pipe is bended or
jammed.
No Replace fuel
pressure regulator
Yes Repair or replace
the harness
18 Check if it is break or short circuit between 1#,
2# pins of crankshaft position sensor and 34#,
15# pins of ECU.
No Next step
Yes Repair 19 Check if the part of air intake system is leaking.
No Next step
Yes Repair or replace 20 Check if air flow meter works normally.
No Next step
Yes Next step 21 Check if the coolant temperature sensor is
working correctly.
No Repair or replace
Yes Remove the
mechanical failure
22 Check if the reason for the failure on starting is
about mechanism, such as much cylinder
clearance, cylinder leaking, and so on.
No Replace ECU
Note: When checking this problem, if all parts in electronic fuel injection system are
normal, consider if mechanical part of the engine works normally, or if cylinder
pressure is normal and if air leakage exists and so forth.
