Also wont prime
If an airless paint sprayer won't prime it's usually because one or both check balls are stuck. First try hitting the head where the pump is sharply with a hammer, hard enough to knock the balls loose but not so much that you do any damage to the pump. If that doesn't free them up you may have to take the pump apart and clean them and their seats.
If an airless paint sprayer won't develop pressure, it's usually because the packing rnigs are damaged or collapsed. The only way to check this is to totally disassemble the pump and check them. Also look for any damage to the piston and cylinder. They must be very smooth and shiney, if they are scored they will eat up any new packing rings you put in.

Your Transducer is shot the 440i has had this problem since inception. Now they are getting part made elsewhere. Your 440i has a four year warranty. it is covered the part if you dont have warranty cost 85.00 US. It is not a hard thing to replace on your own about 12 min. and your set.

i can help if i know the manufacture or had a picture.
quite possibly the lower / inlet ball valve is sticking or has someting stoping it from seating properly. so your fluid is going in and out the inlet.
