om606 engine bad starting problem. after leaving stud for a long time the engine spins fast on the starter. as if it had lost compression .then after a bit it starts to sound normal and then it fires up. after that it is ok until i levee it stud again ? help
 
Sounds like the diesel is running back,

When turning the car over from cold, look at the clear fuel lines to see if diesel is in them or is being pulled through.
 
The diesel lines can cause delayed starting as can poor compression, if the compression is poor after it has been stood and the oil drains off the cylinders then it may need new rings. I would get a compression test done on the rings - wet & dry test should show it up.
