Removing the injector is fairly simple. There is a fuel supply line (steel line) to each injector. There is also a return line (smaller one). Both of these lines will have to be removed. On the return line be careful not to lose the little compression washers. Remove the two bolts that hold the injector in place. The injector should pull out. Be careful not to lose the copper washer that usually comes out with it.

Inspect the end of it. There should be tiny holes in the end where the fuel sprays out.

Unless you have a injector tester you will have to take them to a Diesel mechanic and have them tested. They will hook them up to a machine that can apply the PSI required to see if they are working properly. It shouldn't cost that much.

How do you check fuel injectors?

To check fuel injectors, you can start by listening for a clicking sound while the engine is running, which indicates that the injectors are firing. You can also use a multimeter to measure the resistance of the injector's coil; a typical reading is around 12 to 16 ohms. Additionally, you can perform a fuel injector balance test or use a diagnostic tool to monitor the injector's performance while the engine is running. If issues are suspected, it may be necessary to remove and clean the injectors or have them professionally tested.


What if your 1994 camaro acts like it is not getting fuel you changed the fuel filter what else can you do?

Check your fuel pump and fuel injectors. Have a fuel pressure and flow test done.

Find the fuel line or where the fuel injectors are and fallow the fuel line they are connected to and at some point you will find a connection much like a tire connection that is where you will do a fuel pressure test from


How do you fix a fuel problem on a 1993 Mitsubishi Mirage?

In order to answer this you need to be more specific as to what fuel problem you are having. Is it a fuel pressure problem? or a fuel injector problem. I would suggest you go get the fuel pressure checked to begin with. That can usually tell you if the fuel problem is from the fuel tank to the fuel rail or if the problem may lie in the fuel injectors. A weak fuel pump or a clogged fuel filter may be the culprit. If your pump is good and the filter is clean, then one or more injectors may be clogged not allowing the fuel to get to a cylinder. The fuel pumps job is to deliver the fuel to the injectors, the fuel injectors are designed to deliver the fuel to the engine beit through a throttle body or a bank of injectors or single injectors made for each cylinder. Start with a fuel pressure test and see where that leads and then come back and repost.


How do you test cylinder compression on diesel ingine?

To test cylinder compression on a diesel engine, you'll need a compression gauge specifically designed for diesel engines. First, remove the glow plugs or injectors to access the combustion chamber. Then, insert the compression gauge into the cylinder, crank the engine for several revolutions, and record the pressure reading. Compare the results against the manufacturer's specifications to determine if the engine's compression is within acceptable limits.

After I replaced the fuel filter on my 1994 fleetwood why does the engine still partially stalls when it is under full acceleration at high rpm?

you should check the fuel pressure and volume by preforming a fuel systems test. then if it is satisfactory to the specifications of the repair manual, test the injectors, resistance test and balance test.
