Where is the engine fuel injector located?

[DelReid]

Engine fuel injectors are located on the intake manifold, while direct injection ones are positioned on the cylinder block. Gasoline injectors are components of the gasoline engine electronic control system. The cleaning method for fuel injectors is as follows: 1. Remove the fuel rail mounting screws; 2. Shake the fuel rail gently and remove it to avoid damaging the injector O-rings; 3. Ensure the battery negative terminal remains disconnected; 4. Remove the injectors from the fuel rail; 5. Connect the injectors to a homemade injector plug and wires; 6. Use carburetor cleaner pressure to simulate actual fuel supply pressure; 7. Maintain constant connection between wires and battery positive terminal; 8. Use wire contact with negative terminal along with carburetor cleaner to simulate injection conditions for cleaning purposes; 9. Clean the injector nozzle; 10. Reinstall the fuel rail, paying attention to the position of injector clips and O-rings.
