When the key is the position of on ..fuel pump has no sound ?
any help please

 

What kind of tools do you have to work with ? Test light, meter?

 

When key is first turned to on position then the fuel pump will prime fuel rail for about two seconds
Then it will shut off. If engine is cranking then it will allow the fuel pump to run.
Have you check for spark? Fuel injector pulse? Fuel pressure? Tried to start engine on starter spray?
