Check how long it runs for after switching off as there may be a delay in the system that keeps the motor running until the turbo slows and cools down then shuts off. If it has it will be about 2-3 minutes. Another reason that diesels keep running is that there is oil getting into the air inlet side of the turbo from a failed seal and this acts as fuel going into the cylinder and as diesels do not need ignition spark they will keep running. have it checked out by a specialist who medals in turbo repair and sales.

primay fuel pump is defective and won't allow the secondary pump to build pressure and causes it to die and has lack of power, most likely it started getting gutless before it happened.

thats the fuel drain for purging air out of the system after the supply side has been serviced. Don't mess with it, they like to break. Trust me on this!!!

diesels are not known to be high revving engines to begin with, anyways, it sounds like your turbo is malfunctioning, get it inspected or repaired

There is a oil drain return from the turbo charger to the sump. If the sump oil level covers the outlet into the sump, oil will build excess pressure tin the turbo causing the sealing rings to leak oil in to the intake manifold. This would cause smokey exhaust and loss of oil. Try this. Drain the sump completely, refill with the exact quantity of oil to Mazda spec. Dip the oil and if the new oil level is lower than the full mark on the dipstick, you have found the cause of the problem. Mark this new level with a scriber or file and fill only to this new level. Hope this is the solution.
