Problems that Could Affect the Performance of Your Nissan Maxima Fuel Injector
The Nissan Maxima fuel injector sprays fuel into the combustion chamber of your car's engine. It has long been the primary fuel delivery system in vehicles, which is why a lot of them still have this today. Without the fuel injector, your car's engine can't receive fuel and therefore can't work. When you experience these common symptoms in your car's component, you need to diagnose it immediately.
Considered as the number one problem of fuel injectors, a simple clog can greatly affect the engine's performance as it can cause a "lean" fuel mixture. If you notice that your car is misfiring, then clogging may be the cause of it. Check if your "Check Engine" light is on as well as this often indicates that the fuel injector is clogged.
Clogs are often caused by fuel deposits in the component's nozzle area. If you think one of your fuel injectors has this problem, then add cleaners to the system. You can find these in most automotive supply and repair centers.
While not as common as the first problem, your car's fuel injectors might not work as well due to electrical problems. If your vehicle's engine is not starting at all, then the injector might not be able to make the correct mixture of air and fuel, causing it to misfire or not fire at all. This usually indicates that the component's electrical wirings are faulty or that it needs to be cleaned. If the engine still won't start properly after cleaning the fuel injector, then you'd better check the wirings. Another indicator of an electrical problem in your system is a lit "Check Engine" light.
Other troubleshooting tips
You can find out if one of your car's fuel injectors is faulty through various methods. First, using a mechanic's stethoscope, examine each component while the engine is on. If one of them makes a different tapping noise, then there might be a problem with this particular injector.
Another way is to disconnect each fuel injector one at a time, while the engine is on. So long as you notice a change in the engine's behavior every time you disconnect one, you can move on to the next component. However, if nothing changes in the engine when you remove one, then that particular injector might be faulty.
