If the engine does not get enough fuel sprayed into due to a clogged injector, then the engine will misfire as you drive.

What causes a fuel injector to leak over the engine?

So, the most common cause of leaky injectors is; the failure of the O-ring, where the injector meets the fuel rail. The O-ring can become, hard and brittle, from the heat of the engine. If it breaks, then fuel can leak out, over the engine. The other way an injector will leak is if, the injector body or nozzle cracks.

What causes the fuel pump to not start?

The fuel pump is running and delivering normal pressure to the engine But, with all that working your engine still will not start. So, the most likely cause, is that the fuel injectors are probably not opening. The (PCM) uses the trigger signal from the crankshaft position sensor; and/or camshaft position sensor to pulse the injectors.

What is a bad fuel injector?

A car that has a bad fuel injector will often have a rough, or choppy, engine idle. A fuel injector is responsible for injecting fuel directly into the engine cylinder where it is burnt during combustion; if this fuel delivery is compromised, a rough engine idle can result.

What is engine injector?

An injector is a device for introducing fuel under pressure into the combustion system of an engine. The vibration of the four-cylinder engine cracked a fuel injector pipe. Larger injectors increased fuel flow to the 2.4-liter turbocharged engine.
