What is the effect of defective injector?
A faulty fuel injector can cause the vehicle to experience misfires, a loss in power and acceleration, a reduction in fuel efficiency, and in severe cases can cause stalling or prevent the engine from running at all.
Can a bad fuel injector cause cel to come on?
Although this could mean a lot of things, a bad fuel injector could be one of them. Any time an injector delivers less fuel than needed (or more in some cases), the engines efficiency is lowered and can trigger the CEL to come on. Use an OBD2 scanner to confirm the issue.
What should I do if my fuel injector breaks?
A good kit (like this OTC set) will include various adapters to allow you to work on most fuel injected vehicles. Fortunately, most fuel injector issues can be fixed with a professional cleaning or replacement of the O-rings if a leak exists there. But when a fuel injector cracks or breaks, replacement is necessary and it can be expensive.
What happens when the solenoid of a fuel injector fails?
Typically, the solenoids often short internally when injectors fail, which causes a drop in resistance. If the specification calls for 3 ohms, for example, and an injector measures only 1 ohm, it will pull more current than the other injectors.
Why do fuel injectors lean out when under boost?
When the engine is under boost and at a higher rpm, it needs all the fuel the injectors can deliver. If the injectors are dirty and can’t keep up with the engine’s demands, the fuel mixture will lean out, causing detonation to occur. The leaning out may cause higher than normal exhaust temperatures and turbo failure.
Why is my fuel injector not working on my Nissan Maxima?
If it gets worse you know that cylinder’s injector is working. If the problem does not change then you know that the injector for that cylinder may not be working. It could also be a bad spark plug, bad spark plug wire or a few other things. So make a note of any cylinders that may have been injectors based on this test.
What to do if your fuel injector is not working?
If your injector shows no reading or one significantly outside this range then you have a bad injector. In order to test the two terminals you’ll need to remove the injector’s terminal plug. It’s the type of plug that has a thin metal wire wrapped around it to hold it in place.
What kind of engine does a Nissan Maxima have?
Recently my 1991 Nissan Maxima, with the VG30E engine, was running poorly and was clearly underpowered. I had just had problems with my MAF (mass air flow) sensor so I thought this might be it again. But it wasn’t quite the same problem so I started searching online for similar symptoms in other Maximas.
What should the ohms be on a fuel injector?
Next you’ll need a multi-meter put on the ohms setting. A good injector will measure around 10-14 ohms across the injector’s two terminals. If your injector shows no reading or one significantly outside this range then you have a bad injector. In order to test the two terminals you’ll need to remove the injector’s terminal plug.
Can a TEF-20 have no fuel injectors?
However, it is not uncommon for people to contact us saying they have fuel to the injection pump but cannot get fuel to the injectors. Recently an owner of a TEF-20 wrote in thinking he must be doing something wrong, but he didn’t know what. To use the gentleman’s own words, he was “completely goosed“!
Why is there no fuel in the injectors?
The tractor in question has not been started for three years. It is quite common for the components of a stood injection pump to seize. Inside the injection pump there is a rack which engages with pinion teeth on the elements, rotating the elements which adjusts the amount of fuel delivered from zero to full depending on the engine requirement.
Can a turbo injector be taken out of a car?
Taking out the turbo helps a lot. Some prefer taking out passenger inner fender. Once this done, you can access all injectors almost easely. If you don’t want to bend injector lines, you will have to pull out the intake in order to loosen the lines at the IP.
What should I do if my fuel injector is stuck?
Don’t force it or you will break it, only apply gentle hand pressure to try and move it. If it is stuck then don’t tap or hit it as it will damage it. You would need to take it to a diesel engineers to have the seized element replaced if you have no luck.
