What do you need to change fuel injector in Nissan Maxima?
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. The removal of these plugs requires a steady hand and a little patience.
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.
How much does it cost to change fuel injectors?
If you have a mechanic replace your injectors you probably want to have them all done because it’s probably three hours labor plus gaskets if they have to go back in. But if you do it yourself you can do just the injectors you need and spend three hours of time plus about $10-20 in gaskets. A full set of injectors is $600-750 but it’s up to you.
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.

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.

How much does it cost to replace a fuel injector?
Remove and replace pump – 0.9hrs at $80/hr, $72 As we see, the cost to replace fuel injectors can vary fairly widely depending on what type of repair is needed which can be anywhere from $10 to $200 for a simple electrical repair or injection cleaning service, and it can run much higher if more parts and diagnosis are involved.
What makes a fuel injector last so long?
The biggest contributing factor to fuel injection system longevity is the quality of the fuel being run through the injectors. Fuel only has a certain shelf life (for gas about 1-1.5 years and for diesel, about 2-2.5 years) and must be used before then or else, it can leave a residue on fuel system components.
What can cause a fuel injector to fail?
For direct injection, it includes faulty injectors, high-pressure fuel pumps, leaks, or internal engine damage. Electrical failures affect the solenoid side of the injector, and they can be caused by a failed solenoid winding, bad connection, faulty wiring or a bad ECM.
What’s the difference between multiport and TBI fuel injectors?
It’s fairly easy to diagnose and replace. Multiport fuel injector – It just means there’s a separate injector for each cylinder. This is by far the most common set-up, with some advantages in efficiency over the older TBI arrangement.
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.
Why does my fuel pump run at 43 psi?
With Ignition ON, fuel pump runs for @ 5 seconds at 43 PSI and then shut down automatically. This will allow fuel pressure to build in the line minimizing hard starting problem. You are correct in your search, Scotty. Loss of fuel pressure may be due to faulty check valve (in pump assembly) or Fuel Pressure Regulator-Fuel Injector.
What’s the fuel pressure on a Nissan Leaf?
Now the pressure begins to build, but only 5-10 PSI. After 5 or 6 key ON’s, it finally gets to 43 PSI and holds steady. Now I release the grips to un-pinch the line and the pressure drops fairly quickly, back to 0-2 PSI within a couple of minutes max.
What kind of car is Nissan Maxima SE?
Your vehicle may in fact have slightly different methods so use common sense if the directions don’t match what you see. The demo vehicle being shown is a 1991 Nissan Maxima SE with the VG30E engine. Parts List The following list contains all of the parts you will need to get in order to complete the job.
How big of a tank do you need to clean a Nissan fuel injector?
You need a full tank because the cleaning solution is designed to mix in appropriate ratios, and too little gas in your tank can make the solution too strong. Add 3 ounces of formula for every 10 gallons of gas. One bottle can treat up to 25 gallons of gasoline.
What can I use to extend the life of fuel injectors?
Fuel injector cleaners can extend the life of your injectors, make your car run more smoothly and reduce emissions. Fill up your gas tank, then add a bottle of fuel injector cleaner designed for use in your tank (if you’re using Sea Foam, skip to Step 4).
