My Volvo 940 cannot start after one year of no use. I have change new fuel pump, relay, crank shaft sensor and plugs. I have spark from coil and the fuel is reaching the injector and the engine is cranking well but the fuel is no coming out from injectors. I test the injector direct is shooting out fuel. The wiring is check and no fault is found. What is EMO blocking does this cause the injectors not to work. Please advice Thanks
