will check the voltage in the morning using a meter and also lamp tester, if no light when glow switch position is selected is it the relay

Whatever, but fuse, relay, cable, it's traceable, and if you hot wire it for 20 seconds and then try a start you'll soon know if NO GLOW is the problem.

no when she starts no white smoke

The white smoke I was thinking about is from the tailpipe while the engine is turning on the starter before it fires up and perhaps for 2 seconds after it fires up.

No white smoke suggests the cold start excess fuel device may not be setting. The primary cause of this is the throttle being pressed down even a little. Makes sure the tickover speed is NOT being set by a tight throttle cable

no veggie oil used

no starter sounds ok, no spinning

All these engines are a bit dodgy to start, but great when they are running!
They start fine if, but ONLY if, all the bits and pieces for cold starting are working.

Never Happened To Change The Fuel Filter When You Did The Glow Plugs Etc, Had A Vehicle Once Where The Centre Seal In The Filter Had Not Been Fitted, Probably Guy Dropped It On Fitment And This Allowed The Fuel To Drain Back When Left For Any Period And Took Loads Of Cranking To Get It Going. Bought Mine Recently And Seemed To Be Suffering From This As Well, But Not So Bad So Took Filter Off. The Centre Ring Had Been Displaced Slightly Causing Slight Damage, New Filter Solved It.
