What does a cylinder missing mean?
Damaged, worn, or bad spark plugs, or a weak ignition coil can cause a loss of spark, and therefore, a misfiring cylinder. If there is not enough gasoline in the air/fuel mixture, this can cause a misfire as well. Sometimes cylinders have intermittent misfires, which means the cylinder does not misfire all the time.
Can a bad injector cause a dead cylinder?
Bad injectors A failing injector could be the cause of a dead cylinder. It may be over-injecting, not injecting gasoline into the intake manifold, or directly into the combustion chamber.
What happens if the fuel injector doesn’t close?
If the injector can’t close, cylinder performance is compromised. Whenever the fuel injector pump’s O-rings or ball seats are defective, the timing of the fuel transfer process is disrupted. This is a common diesel fuel injector pump glitch, and usually requires a complete injection pump rebuild or replacement.
How do you remove the injector Unit Pump?
Thread the impact extractor onto the top of the injector unit pump, where the injection line was installed. Pull the injector unit pump out by using the slide hammer on the impact extractor. Do not use excessive force that could damage the threads on the injector unit pump fuel line connection. Check the injector unit pump for wear or damage.
Why do I have a problem with my fuel injection pump?
Fuel injection problems, therefore, are one of the most pressing engine issues to deal with. Whether you’ve experienced fuel injector failure or not, it helps to understand the fuel injector pump, how it relates to engine performance, and also how diesel fuel injection pumps differ from traditional gasoline-powered units.
Why are unit injector and Unit Pump Systems less troublesome?
Reduction of line dynamics problems: line dynamics difficulties in unit injectors/unit pump systems are less troublesome than in their pump-line-nozzle (P-L-N) counterparts. The possibility of wave superposition—which troubled the P-L-N systems by causing after-injections and contributing to injection delays—is greatly reduced.
