ok will do croppie but as i got a constant good pump pressure would that not indicate pump as fine if not what should i be looking for. thanks for your help

Have you checked the flue seals? If they are degrading and allowing combustion gases into the air intake and back into the combustion chamber you will get smoke and poor performance. Take the intake hose off the burner, bung up the flue, take the lead off the solenoid to prevent firing, drop a smoke pellet in the burner, let the fan run and you will see if there are any leaks as smoke will pour down the air intake hose. Might be a contributing factor to motor failure. Check the pump isn't seized too. Can the motor be set spinning when energised (using a pencil on the fan not your fingers) or is it sluggish? If so, replace it.

Run that by me again?

ok thanks whpes i will try smoke pellet

Check everything, could be more than one failure mode

update for you all. replaced capacitor today as motor had stopped now motor running fine and very little smoke. so looks like it wasn't giving anoth power to motor which in turn wasnot driving fan fast anoth to pulling correct amount of air.

The capacitor is only there to start the motor and in proper direction. A perfectly functioning motor with a faulty or missing capacitor will work no problem if you spin the fan to start it.
I wouldn't think the capacitor is the only problem.

well its done the job in this case so im happy as is customer

Strange one. I have never known a burner motor to perform better with replacing the capacitor. They just will have a nice sharp start up.
Just be careful the oil pump isn't dropping pressure the longer if works, or the motor is running slow.

ok will do thinking about it does the power not run through the capacior constantly to the motor but get step up to start off
