Check the supply voltage to the fuel injectors
Arrangement of an electric connector (1) applying a voltage to the fuel injector and the connector (2) on the fuel injector
The LED does not flash in any of the cylinders
Pin connector on the electric power supply to the fuel injector
| PERFORMANCE ORDER | | 1. Connect the control LED to pin number 1 electrical connector for the power supply to the fuel injector and the weight of the car, see. Fig. Arrangement of contacts in the electric power supply to the connector of the fuel injector. | | 2. Connect the contact number 2 electrical connector with the mass of the vehicle. | | 3. Turn the crankshaft of the engine starter. This LED should blink. Otherwise, check all the electrical power circuit of the fuel injector. |
|
The LED is flashing only on one or more cylinders
| PERFORMANCE ORDER | | 1. Check the electrical power supply circuit of the fuel injector and to identify and eliminate a place of breakage or short circuit it to ground. | | 2. Check the operation of the engine control unit. |

Check resistance
Designated connect an ohmmeter to check the resistance of the fuel injector
| PERFORMANCE ORDER | Consistently disconnect electric sockets from fuel atomizers and, using an ohmmeter, check the resistance of the fuel injector, which should be in the range of 12 to 17 ohm cm. Fig. Designated connect an ohmmeter to check the resistance of the fuel injector.
A warning  On the engine warm up to normal operating temperature, the resistance of the fuel injector increases by 4-6 ohms.
If the resistance of the fuel injector is not correct, replace the fuel injector. |
