Hi

car came into garage has a none runner checked for codes came up with p0087 pressure loss in system carried out back leakage test,checked pressure out of pump no pressure build up checked with local ford dealer,without telling to much they say it may be pump or pcm bring it to workshop,being a siemens vdo pump there his not a lot of info out there so we have decided to remove pump and get it tested this his were the problem lies looked simple at first but there his a chain driving the pump and we are just a bit concerned it may drop off the pump so if anyone has changed the pump we would be most thankful for this info.thanks terry
