Along with how quickly it goes snap\click, will tell if its hangin up!
pull the cover off of the injector pump and make sure the shutoff spring has tension and arm not binding. 12 volts energizes coil, lack of 12v and the mechanism should freely move the other way.I just run diesel. No propane or anything like that. It doesn’t sound harsh or anything just continues to run. So if fuel is continuing to get in would it be the injectors or the pump?
It's inside the top of the injector pump. It's electrically activated to either let fuel flow through your IP or not (which shuts the engine off).fuel shut off solenoid?
