Check the wiring at injector . Generic check ,
Inspect the electrical connector on the fuel injector. Look for bent or pushed out pins. Install some dielectric grease and push the electrical connector on the fuel injector. Make sure it is a tight fit and the metal spring retaining clip is in place Start the engine. Place a long screwdriver handle to your ear and the tip on the fuel injector. A clicking sound indicates a working injector. No sound is the opposite Disconnect the fuel injector. With an ohmmeter, check the resistance between the two male terminal blades. A good injector will have 0.5 to 2.0 ohms. More or less ohms indicates an injector with an internal short.If not that , probably injector knacked / needing cleaned . Could try injector cleaner additive .
