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 should temperature be when fuel injector is stuck?

While the engine is warm, use a laser thermometer and point it at the exhaust manifold pipes. Each cylinder should read plus or minus 30 of 450F degrees. An injector that is stuck closed will give you a reading of 200 to 250F, and one that is stuck open will cause the temperature to rise up to 600F or more.

How does a fuel injection system work in a car?

Fuel injection systems either work via a throttle body containing as few as 2 injectors, or go straight into the port with one injector per cylinder. The injectors themselves spray gas into the combustion chamber like a spray bottle, allowing the gas to mix with air before ignition. The fuel is then ignited and the engine keeps on moving.
