Check the power supply system of the engine
The main indicator of health of the power supply system of the engine is a fuel pressure in the fuel rail. But first we recommend to check the condition of the air filter (see. "Replacing the air filter element"), as this operation is simple and will not take much time. Once you make clean the air filter, check the electrical contacts in the stocks-to-wire fuel injection system components responsible for the supply of fuel (fuel module, switch the fuel pump, injectors). Check the fuel pressure in the fuel rail of the engine is possible only with a pressure gauge with a set of adapters. 1. Turn the ignition on and listen. Within a few seconds you should hear the sound of elektrobenzonasosa fuel module. If it is not heard, check the electrical power supply circuit of the pump. |
A WARNING Keep in mind that elektrobenzonasos not included, if there is pressure in the fuel system. That is, if you previously have included ignition and tried to start up the engine, defective pump has had to build up pressure in the system and its failure to include in this case is not a malfunction. |
| 2. To determine the value of the fuel pressure through a special adapter plug gauge with measuring limit of 10 kg / m 2 with. When idling engine nominal pressure in the fuel should be 3.5 kg / cm 2. |
Reduced pressure may occur for the following reasons: - Faulty fuel pressure regulator 2 and clogged fuel filter 1, installed in the fuel module; - Clogged fuel fine filter; - Faulty fuel pump.
