It should switch off after a second or so. If it doesn't then you may have a faulty rpm relay. >2. I was testing the #3 fuel injector.

Do the other injectors turn off? You shouldn't test one injector while all the others are still mounted as you'll be filling the inlet/cylinder up with fuel.. Sounds liek a faulty metering head. If they all carry on spraying, it's the plunger, if one carries on spraying, it's the head.
