Reasons for failure

1. A possible cause hard starting a hot engine could be insufficient fuel pressure and fuel leaking from the injectors.

2. If the nozzle does not work when you scroll through the engine starter, check for the following conditions:

- Failure of the power supply circuit or a computer circuit connection with "weight";

- Failure of the main engine control relay;

- Failure of the crankshaft position sensor and camshaft position sensor.

3. If the engine idle speed does not change when an inverter is disconnected injector, check the following in the corresponding cylinder:

- Injector and wires;

- Spark plugs and high voltage wires;

- Compression in the cylinder.

4. If the injection system is working, but the duration of the injection is not correct, check the following conditions:

- It is fully combusted mixture (whether operable spark plugs, ignition coil, whether the normal compression in the cylinders of the engine, etc.).

5. The warning light illuminates on the instrument or HI-SCAN displays a fault code in the following cases:

- Faulty nozzle itself.

Check

Operability test

The instrument HI-SCAN:

- Alternately turn the nozzle;

- Check the length of the fuel injection nozzles.
