To determine which fuel injector is not working, you can perform a few diagnostic tests. One common method is to use a multimeter to check the resistance of each injector; a significant difference in resistance indicates a faulty injector. Additionally, you can use a stethoscope or a mechanic's stethoscope to listen for clicking sounds when the engine is running—if an injector is silent, it may be malfunctioning. Lastly, observing engine performance issues or using an OBD-II scanner to check for specific error codes can also help identify the problematic injector.
i dont kmnow do you charlie
replace harness and use lucas injector cleaner.
dint kmnow bt something
There are two injectors at the top of the throttle body. If you can see that one works and the other does not, then replace the nonworking injector
rough, with poor fuel economy.
possible problems are: The fuse is blown, or the injector is bad, or the wiring to the injector is bad, or the computer is bad
Locate which cylinder is dead, remove the spark plug, if the spark plug is bone dry the injector is probably not working.
If you mean the fuel injector for the #4 cylinder isn't working the answer is simple, either the injector is bad and needs replaced, or the connector has gone bad/ the wires are shorted out. Put an injector pulse tester on that injector (most people don't have these so you'll need to get it tested at a garage), if the injector doesn't fire when it's tested separatly you need an injector. If it does fire that means the plug/wire is the problem.
Feel the exhaust manifold at each cylinder as it is running, if an injector isn't working the manifold at that cylinder exhaust port won't get hot. Some of those Ford diesels had a problem with the electrical connection where the injector harness passes through the valve covers.

where on a 1995 ford f250 7.3 engine is the number 8 fuel injector located I have hod a buzz test done on the truck thay said the number 8 fuel injector was not working so I need to know wrere is the number 8 fuel injector is located
I would suspect either a clogged fuel filter or a defective or not working fuel pump.
