Step Operation
1 Turn ignition switch to "ON", and check with scanner
to see if there is any failure information recorded.
2 Unplug cylinder wire and connect spark plug to make
spark plug electrode 8-10mm away from engine
body. Rotate engine with starting motor and check to
see if there is blue or white high voltage spark
(notable spark does not prove that he spark plug is in
good condition, for the resistance value of the
atmosphere differs from that of compressed air in
cylinder).
3 Check resistance value of high voltage wire to see if
it is normal.
4 Check high voltage wire and spark plug of each
cylinder to see if they are damaged.
5 Check the connection between ignition coil and ECU
wire harness to see if it is damaged.
6 Check ignition coil to see if it is in normal condition.
7 Check socket connector of crankshaft position sensor
to see if it is properly connected.
8 Turn ignition switch to "ON" and check fuel pump
relay and fuel pump to see if they work normally.
9 Connect fuel pressure gauge valve. Strap Pin 30 and
Pin 87 of fuel pump relay, start fuel pump and check
fuel pressure to see if it is around 350kPa.
10 Pull out fuel distributing pipe and injector together,
and unplug injector connectors from wire harness one
by one. Supply 12V voltage to injector directly from
accumulator and check if injector works.
11 Clean injector and recheck to see if it works.

water.
