The general procedure of diagnosis:
Serial
number
Operation steps Test
results Next step
Yes Next step 1 Connect the fuel pressure gauge (access
point for the fuel distribution pipe assembly
inlet pipe end), start the engine, check the
fuel pressure in the idling condition is about
3800kPa
No Maintenance of oil supply system
Yes Next step 2 Set aside seven minutes a cylinder cylinder
line, connected to the spark plug, spark
machine from the engine body around
5mm, start the engine, check whether there
is a blue and white high pressure fire
No Maintenance of the ignition
system
Yes Repair or replace the sensor line 3 Pulling off the coolant temperature sensor
connector, start the engine, the engine is
successful up observation.
（
Or a 2500
OHM Series in the coolant temperature
sensor junction resistance to replace the
