Now I have to figure out which road to take, new/refurb pump, second hand pump, park patrol up for a bit and find a td42 donor car.
If I were to go new pump it would be silly to not go injectors also?
If your going to get rid of it you could go second hand, but not if you intend to keep it, basically if you are happy with all other aspects of the vehicle, why not hang onto it. As Muzz says if there has been no problem with your injectors then no need to replace them at this time.
Do a google search for Bosch IP agents/repairers, there is one down the road from me so there could be one near you as well to contact and have a chat.
We don't know what your rough location is so it's hard to recommend a place. In the top RH corner of each post you can add a location by going into UserCP, this helps us to help you, you can see it in mine and Muzz's posts.
