Its easy to test to see if the injectors are stuck. Just get a 1.5V Volt single cell D battery or similar and make one permanent connection to the injector and with the other connection flash
it on and off the battery " quickly" and listen for a click. If you hear a click you will know the injector is not stuck.


The reason using a 1.5 Volt battery is you are limiting the current. Putting a 12 volt car battery across the injector may damage the injector.

If I don't hear a click with the 1.5 Volt battery I will then slowly increase the voltage and in most cases I have managed to free up a stuck injector.

Many cases I have had all 8 injectors stuck and managed to free them up using this method.
