Hi, Its a 1991 1.9d 1x, It started playing up about a week ago and got really lumpy and poor power when setting off and took a while to start running correctly etc. then yesterday it would not start at all. Anyway I checked the cambelt which was in relatively good condition apart from it being loose. i then checked the timing and it was way out, removed belt to adjust cam and fuel pump. connected it back up and went to turn crank pulley by hand and just before the first revolution it just locked up, same if i turn it backwards? Any ideas?
