When in storage, the first thing to dry out in those DB or JDB pumps is the metering valve. The metering valve is what shuts the fuel off. It is pushed shut - when you turn the key off - by springs. When you turn the tractor on - an electro-magnet overrides the springs. So - since you hear the clicking - all it means is the electromagnet is working - but the metering valve is likely stuck closed. There is NO mechanical connection between the two.
