Common Fuel System Problems

Humans have been designing and developing fuel engines for decades now, and the reality is that for decades to come, we will still be designing fuel engines. As long as engines remain, problems are bound to arise at some point in time. This article focuses on common problems fuel engines typically experience and how to quickly identify them.

Fault Fuel Pumps

Faulty fuel pumps There are several tell-tale signs of a faulty fuel pump. While some are obvious and easily detectable, others aren't. One of the most obvious sins is a loud electrical clicking or whining noise produced by the engine even when idle. Another is if your engine is hard to start, and you're sure your starter motor is in good condition. This may be a sign that the pumps are struggling to get fuel to the engine. Misfires or sudden decreases in power while driving is another indication of a faulty fuel pump. If you experience one or all of the above, it'll do you much good to get your fuel pump checked.

Fuel Filters

Fuel filter works to prevent contaminants from getting into the fuel injector which ultimately could affect the smooth running of your or even damage it. This small engine part serves a significant purpose that could affect the life span of your engine. In some modern engines (cars especially) inspecting the fuel filter can get technical, however, there are signs to look out for to know if something isn't right.

The most obvious is a lack of responsiveness from the engine or hesitation when you apply the throttle. If you experience any of the above it could be caused by a blocked or faulty filter which in turn restricts the flow of fuel into the injection system.

Bad Fuel

Cheap fuel is always bad, the problem, however, is knowing the bad one, especially for your engine. Sometimes it isn’t your engine fuel system that is faulty. Your engine could be reacting to poor-quality fuel. Bad fuel affects your engine in a lot of ways, the top is performance. You may experience sluggish performance or starting difficulty, especially if your car has been at rest for a long period (overnight mostly). In more extreme cases your engine may experience misfiring or backfiring which could trigger the engine management warning light. If you suspect your engine's poor performance is due to you poor quality fuel, we advise you find a way to rid of this fuel and stomach the loss rather than risking your engine life further in a bid to exhaust your purchase.

Fuel Injector

Fuel injectors problems are relatively easy to notice, even if it's one of the injectors that's developed a problem. The symptoms can range from having difficulty in getting the engine to fire after starting, fluctuation in the revs or a rougher speed performance (jerking of the engine). Another indicator of a faulty injector can include a sudden spike in your engine's fuel consumption compared. Getting your engine checked is highly recommended at this stage.

Fuel System Cleaners

Fuel system cleaners are different from filters and shouldn't be confused for each. While filter prevents contaminants from getting into the injector, cleaners help with the thorough cleaning of your engines. Another major difference is that filters are usually built into the engine, bit cleaners are a third party that you introduce manually, most times through the fuel tank and, it works its way through the system. Contaminants are known to settle at the bottom of your tank over time, which is why it is recommended that you don't run your vehicle to empty. Cleaners help to bridge your tank of such contaminants.
