How do I repair Fuel injectors


What you have is a misfire,Spark or fuel,if this is injector due to storage then you have rotton gas, add a gallon atleast of gas, put a bottle of fuel injector cleaner dont worry about the level of gas.start the vehicle leave the idle at 1500 RPM to 2000RPM for one minutes.That should take care of it. Now you need to inspect the vehicle for disconnected vacuum hoses.Injector dont plug that easy yes it fails and yes they do plug due to todays returnless fuel line,but what if its the ignition coil? Can you access the front coil and see if it the sparkplug boot is oil soaked?If you have a ignition misfire the check engine light comes on and disables that injector,until it see a restart. I am going to agree with you you say it is fuel injector when you get a chance replace the fuel filter

Replace your fuel pump. When you run a vehicle completely out of fuel, you will pull all the sediment off the bottom of the tank, and this will indeed clog fuel injectors, but first it will clog your fuel filter. After replacing your fuel filter, purchase a high-octane fuel injector cleaner, and add it to your fuel tank as specified on the side of the fuel injector cleaner bottle specifies.

Yes, if everything is still connected properly, except that the injectors are no longer seated int he valve head, then you should see little spurts of gas coming from them when the engine turns over.

Be aware though, that it might not be your fuel injectors that are the problem. You need to finish checking the rest of the car before making that assumption.

Once you know the injectors aren't firing, you need to check the fuel filter and the fuel pump to make sure the gas is getting from the tank to the injectors.

You should have a fuel filter located on the passenger side of your car near the gas tank. Follow the gas lines under the car to find it. It is good to change it anyways, but you can check to see if gas is coming from the tank to the filter by removing the rear line

** BE CAREFUL, Gasoline is EXTREMELY irritating to the eyes and skin, and it WILL come out when you remove the line from the filter***

If it is coming from the tank to the filter you don't have to check your pump. Then replace the rear gas line, and remove the front gas line going to the engine and make sure the filter spits out gas while the engine turns over as well.

If there is no gas getting to the fuel filter, you will need to check your fuel pump, which should be located inside the gas tank. You can check it by getting under the car while you have a friend turn the key to the "on" position, but not starting the car. Do this 4 to 6 times to make sure you hear a little "Click, woosh" type sound that lets you know the pump is triggering.

If you have gas coming from the tank, through the filter and it is still not coming through the injectors, then you will need to rebuild your fuel injectors.

This is not hard to do, and consists mostly of changing the little gaskets in the injectors. But be aware that there are lots of small parts and the job cannot be rushed. Also be aware that lumina fuel injection systems are very sensitive. Make sure to disconnect your battery cables before removing the injectors from the system.

Engine wont stay running. Please help.


change the filter first. IF the pumpwas bad it wouldnt start at all. It could be going bad but the only way to really test it is to pull your gas tank and at that rate you may as well replace it.

you could have a clogged injector causing the lack of fuel as well. you can try injector cleaner, Lucas is my personal preference I use it at every fill-up. 4-6oz per tank of gas depending on your tank size.

Cannot get 1987 chevy van 20 to keep running... stalls out


Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.

No gas going through fuel pressure regulator on 1995 dodge carava


I doubt the regulator is bad, the fuel pressure regulator is after the injectors in the return stream to the tank, more likely it is the fuel pump.

hi unlikley to computer on the fuel rail there is a pressure relief control valve some are operated by vacuum so check the hoses some are electrical this controls fuel to all injectors it may be open all the time and fuel going straight to the return to the tank if this is the case there is no pressure for the injectors to work the individual injectors you can buy a tool that fits on the injector and connecting loom thats not dear so it lights flash as the pluses open the injectors or get a multi meter the wires that fit on the injector one is ground usually [black or brown] and the other is a 5v live when cranked yates210456
