Started to have a problem with my freelander td4 51 reg. The first time I noticed a problem was when it took a little longer to start than normal, after a few cranks of the engine it fired up and I drove home. Next time I came to start it from cold, again it took longer to start, so In checked glow plugs....all ok. Then the other day it started as normal I drove about 1 mile then a small amount of smoke came out of the exhaust, the engine management light came on and when I stopped the engine it would not start again. I have checked both fuel pumps, both ok. But I have noticed that there is no movement of the rev counter when trying to start could this be a crankshaft sensor problem? Does anyone have any suggestions?
