To test if a fuel injector is working on a Ford F-150, you can disconnect each injector carefully. Use a multimeter in Ohms mode to test each injector, and the reading should be between 11 and 18. It's also possible for an injector to become blocked with debris or grease, but this is uncommon. If you suspect this issue, it's more challenging to diagnose. You may need to remove the injector from the rail for inspection. It's not advised for inexperienced car enthusiasts to do this, so it's better to have a professional mechanic check the injector at a shop.
