Unplugging Fuel Injectors: A Quick Fix Or A Dead Car?

Clogged fuel injectors can cause engine problems and prevent your car from starting. Without enough fuel, the engine will become starved and you'll notice misfiring, sputtering, and hiccupping. Severely clogged injectors will cause the engine to stall and you might not be able to get your vehicle started.

Clogged fuel injectors can cause engine problems and prevent your car from starting

Clogged fuel injectors can cause all kinds of engine problems. The fuel injectors are what spray the gasoline that is pumped from the tank by the fuel pump into the cylinders or intake manifold. Your vehicle needs this gasoline or diesel fuel in the cylinders in order to start and run. If the engine light on your dashboard is flashing or illuminated, it could mean a number of different things that require immediate attention, one of them being a dirty fuel injector. If the Check Engine Light comes on, it could mean that the fuel injector is dirty or malfunctioning and supplying too little or too much fuel to the engine.

Severely clogged injectors will cause the engine to stall. In fact, you might not be able to get your vehicle started if the injectors are completely clogged. This is because there is zero fuel making its way into the cylinders in the combustion chamber. Without fuel, the spark plugs can only attempt to ignite air, which they will be unable to do.

Professionally cleaning the fuel injectors will remove the dirt and carbon deposit and open up the fuel flow again. The fuel starvation that results from clogged fuel injectors will also cause your automobile to idle very roughly.

Running out of gas can also lead to fuel injector issues. If the engine has started to hiccup or sputter while you drive, it could be the fuel injectors. If they are clogged, your engine isn’t getting all of the fuel it needs to run. Consequently, the engine will become starved for fuel and you’ll notice misfiring, sputtering, and hiccupping as a result.

It's rare, but in some cases, fuel injector issues can lead to engine failure that prevents your car from starting.

The fuel starvation that results from clogged fuel injectors will also cause your automobile to idle very roughly. The same thing that happens while you’re driving causes the engine to sputter while you’re sitting at an idle. Basically, the engine is struggling to prevent itself from stalling because it doesn’t have enough fuel to keep running. Severely clogged injectors will cause the engine to stall. In fact, you might not be able to get your vehicle started if the injectors are completely clogged. This is because there is zero fuel making its way into the cylinders in the combustion chamber. Without fuel, the spark plugs can only attempt to ignite air, which they will be unable to do.

What little fuel that is making its way through the clogged fuel injectors is firing up the engine but only in spurts. Clogged fuel injectors will also cause your vehicle to idle roughly. Rough Idling is typically characterized by varying revolutions per minute (RPMs), even when you have your foot off the gas pedal. Sometimes, rough idling is accompanied by engine stalling — a sudden stop in RPMs and engine noise that feels like running out of gas on a hill. Dirty fuel injectors are only one of several engine problems that can result in rough idling and engine stalling.

Running out of gas can lead to fuel injector issues and engine failure

If your engine is receiving an insufficient amount of fuel, it is likely to misfire. If you are noticing engine misfiring issues, this can be down to dirty or clogged fuel injectors or an injector that fails to open. The most common causes of injector problems are poor maintenance and general wear and tear of the injectors in your vehicle.

If the fuel injectors are clogged, your engine isn’t getting all of the fuel it needs to run. Consequently, the engine will become starved for fuel and you’ll notice misfiring, sputtering, and hiccupping as a result. Severely clogged injectors will cause the engine to stall. In fact, you might not be able to get your vehicle started if the injectors are completely clogged. This is because there is zero fuel making its way into the cylinders in the combustion chamber. Without fuel, the spark plugs can only attempt to ignite air, which they will be unable to do.

Prolonged fuel starvation can lead to internal engine damage or damage to the catalytic converter. Fuel injectors can be inspected and tested to determine if they should be replaced or cleaned.
