While functioning, anoverhead camshaftoperates a low-pressure fuel delivery pump. Subsequently, it supplies diesel to the fuel ducts in the cylinder head and into the inlet port of all injectors. To drive the plunger pump inside the injector, it uses a shared camshaft. This design can deliver...
It doesn't take much of a restriction in an injector to lean out the fuel mixture. A restriction of only 8% to 10% in a single fuel injector can be enough to cause a misfire. When this occurs, unburned oxygen enters the exhaust and makes the O2 sensor read lean. On older multiport...

Use an ohm meter to check your fuel injectors (with the engine running), by removing the wire from the injector. Two metal prongs sit inside the connector. Set the meter for the ohm setting. Touch the red meter lead to one contact and the black lead to the other prong. The ohm resist...
A fuel pump sends the petrol to the engine bay, and it is then injected into the inlet manifold by an injector. There is either a separate injector for each cylinder or one or two injectors into the inlet manifold. Traditionally, the fuel/air mixture is controlled by the carburettor , ...
