Hi all,I have a 53plate transit pick up.It has the 125 engine in it.My problem started when the engine suddenly cut off.The diesel light had come on 15miles back so naturally I assumed the diesel had run out.Was already approaching an Asda Fuel station so just pushed it in.Filled up with diesel.I noticed soon after I used their pump one of them came and put cones on it to stop anyone else using the same pump.I didnt think much of it then.Nway,tried to bleed the diesel and when it was flowing out of the injectors I nipped them up.It still wouldn't start.Nway drained out the fuel suspecting it was contaminated but I used the same fuel in a Merc that was in my garage and out of diesel too and the Merc ran perfectly well.Changed filter,flushed the system,fresh diesel but still wouldnt start.however with a bit of Brake cleaner the engine fires up,smokes badly for a few mins then clears up.I can use it the whole day as long as I dont switch it off.Once I turn it off it wont start unless I use the brake cleaner.Its a vicious cycle.I also noticed I I let it idle on its on it lasts about 2 mins then cuts out.Tried bleeding till no air at injectors,filled up filter manually etc but still only starts on brake cleaner.My local garage reckons the pump is gone???If it was an airlock surely it would clear after a day of driving?Also noticed the truck is lacking power,only goes up to 60mph when previously it would comfortably do 80-85.Please help
