Hi all, I have been a galaxy owner for a year now and really happy until now. I have a 99 tdi Zetec model and since boxing day I haven't been able to start it. I went out to the car boxing day morning ready to go to my parents, but it wouldn't start. I had to eventually get it started by jump starting it. Once started I got the family in the car and set on my way. After a while it seemed to lose power. I pulled over switched it off and restarted, It would then rev up as normal so we set off again. A short while after it happened again. So we stopped again restarted it again and off we went. It continued to happen time after time and it seemed to be running and revving up fine until the revs dropped under 2300. Also when it lost power there was a cloud of smoke coming from the exhaust and when it finally revved up again it didn't smoke at all. I finally got to my parents and stopped the car. When I returned to the car it wouldn't start and hasn't since. Now when I turn it over there is smoke coming from the exhaust as though it is getting fuel but not igniting. I have changed the fuel filter as I thought this could be blocked but sill no joy. I have borrowed my mates diagnostic machine and it came up with a few faults one of which was "injector start valve N108 shorting to ground intermitent" I have been to ford and asked about a injector start valve and they looked at me blankley. The only two parts that are available are the fuel cut off valve and the solinoid valve. I have run a new power feed to the cut off switch which seems to click as if is working so now im stuck. I have cracked the pipes on the injectors and fuel is coming through but it still wont start. Can anybody help me ??????????? Thanks for your time reading this
