 Use diagnosis tool
1
voltage
detection of battery
voltage
 Use fuel pressure
gauge connected in
series between the
injector and the
pressure regulating
valve
 Main switch ON but
not start engine
Fuel
2
 Check fuel pressure
pressure
 Start engine (Idle)
 Check change of fuel
pressure
 Throttle several
rotation
 Check to the change
of fuel pressure again
 The spark plug
removed from the
cylinder head but the
Ignition
power lines still ring
3
 Start engines or use
state
for the diagnosis tool of
output view spark plug
ignition conditions
 Diagnosis tool to
Engine
4
detect the use of
vacuum
 The injector removed
from the throttle body
but not dismantle
pipeline
 Main switch ON but
not start engine
 Investigation the
Injection
5 injector it's leaking
state
fuel?
 Start engines again or
use for the diagnosis
tool of output function
 Check injector fuel
injection and the
injection situation
 Use of diagnosis tool
existing fault detection
code or historical Fault
Code
 Eliminated of the
Fault Code
implementation of fault
6
Detection
codes, check can be
eliminated
 Start engine again
 Check fault is it
happen again
Notes: 1. Fuel pressure gauge connected between the fuel tank and injector, open the main switch to
repeatedly shut down, fuel system makes pressure stability.
2.Injector and injector cap tightly by hands, fuel spills should not be the case.

Test items Determine benchmarks
 Battery  Battery voltage = 10 V
above
 Open the main  Open main switch but not
switch but not to start:
start the engine of Pressure = 250 kPa (stable
pressure value)
 Pressure in Idle  Idle state:
 Rotating throttle,
Pressure = 300+/-6 kPa
(Beating situation from top
situation of
to bottom)
pressure changes
 Rotating throttle moment:
Pressure=300+/-6kPa(sligh
tly beating)
 Spark plug  Specifications: NGK-CR7H
 Ignition conditions:
specifications
 Whether the
With traditional engines
spark plug ignition found ways
 Spark plug sparks
whether it is
normal strength
 Manifold pressure  Manifold pressure = 32~38
of diagnosis tool kPa
 Open the main  Not started, Injector not
switch but did not leaking fuel
 In started, the injection
start engine the
injection situation
state must show fan shape
 Injector state
when start
 Diagnosis toll of  Without any residual Fault
the fault code is it Code
 If residual Fault Code,
can be eliminated
 Start engine, the
according to the "Fault Code
fault is it will Maintenance Form"
happen again implementation of
troubleshooting
Fault reasons
 Battery electricity
 Battery connector
loose
 Harness circuit
opening
 ECU coupler not
connected properly
 Fuel not enough
