Bad Fuel Injector

Examining the cause of a faulty fuel injector in the Coleman 550 UTV can provide insight into the potential solutions for this recurring issue.

One of the most common symptoms of a bad fuel injector is the inability to idle correctly, hard starting, and loss of engine power.

Factory fuel injectors in the Coleman 550 UTV are not well-built, leading to frequent issues reported by owners. As a result, many owners have resorted to purchasing aftermarket fuel injectors to replace the factory ones.

To fix a bad fuel injector in the Coleman 550 UTV, it is recommended to replace the factory fuel injector with an aftermarket one. Aftermarket fuel injectors are designed to be more durable and reliable than the factory ones. This will help to ensure that the engine runs smoothly and efficiently.

Additionally, proper maintenance of the fuel system can help prevent future issues with the fuel injector. Regularly cleaning the fuel system, replacing the fuel filter, and using high-quality fuel can all help to ensure the longevity of the fuel injector.

Engine Issues

Coleman 550 Engine Issues

Engine issues in the Coleman 550 UTV can be caused by various factors, leading to symptoms such as sputtering, stalling, and difficulty starting. One potential cause is a gummed up throttle body, which can occur due to the accumulation of debris and oil. This can be resolved by removing the throttle body, spraying it with a specialized cleaner, and opening the electronic controlled throttle blade.

Another cause of engine issues may be the seat belt safety feature, which can cause the engine to shut off when the seat belt is not buckled. This feature can be bypassed by using a seat belt blank or by buckling the seat belt behind you.

It is important to note that engine issues may also be caused by old fuel, worn spark plugs, or valve problems. The Hisun stock batteries are known for draining quickly, which can also lead to difficulty starting the engine. Regular maintenance and inspection can help prevent these issues from occurring, as can avoiding short trips that don’t allow for proper engine warm-up.

By addressing these potential causes, owners of the Coleman 550 UTV can help ensure that their machine runs smoothly and reliably.

Other Mechanical Problems

Another potential issue that owners of the Coleman 550 may encounter is overheating, which is a frequent problem caused by factors such as temperature sensor malfunctions, air blockages in the coolant system, or blown head gaskets. Interestingly, the factory-set fan switch on Hisun engines in the Coleman 550 does not trigger until reaching higher temperatures, leading to overheating in warmer climates.

To address this issue, some owners have installed a toggle switch on their dash to bypass the temperature sensor and turn on the fan as needed. Others have rigged their machines so that the fan automatically engages and runs constantly when the engine is on. Additionally, an air bubble blockage in the coolant system can cause overheating, which can be fixed by burping the air out of the system. If excessive bubbling out of the radiator fill cap area persists, there may be a blown head gasket.

Aside from overheating, the Coleman 550 may also experience problems with its clutch and fuel system. Proper clutch maintenance is crucial to avoid issues such as worn-out clutch shoes, which can cause clutch problems and affect the overall performance of the vehicle.

Meanwhile, upgrading the fuel system can help address issues such as bad fuel injectors and fuel pump problems. Hisun stock fuel injectors are not well-built, so some owners resort to purchasing aftermarket fuel injectors. Testing the fuel pump is also essential in case of loss of speed and acceleration, idling issues, or engine failure to start. Removing the hose and starting the machine to see if fuel sprays out can help identify fuel pump issues, while inspecting the relay for any corrosion or deterioration can help determine the cause of the problem.
