Hi,
I have a Citation 3L TD 1999, and when is cold, I have to turn over the engine for ages, then it fires up and sometimes dies. When it starts, there is a mass of grey smoke. Starting from a warm engine is fine, without any problems and smoke. The car has done 50000 miles and I have had her from new. I have had it to the garage twice, but they cant find the problem. I know the engine management system only allows the engine to start when the oil pressure has built up, but the oil pressure appears fine. I have had a total of 5 Troopers and this is causing me major problems. Thanks in anticipation. Michael.
