Sounds like the pump or regulator are past it then

Best bet is to try a brand new regulator. I cleaned mine and it worked a bit and then died again. I bought one of the Bosch ones on ebay from Poland. Arrived next day!

Just make sure you get a new O-ring for the top of it (or reuse your old one - I did) since replacing It I have done 300 trouble free miles
