cheap ass glow plugs.... HELP PLEASE

Glad you got it started Mike...

Excellent. Ready in time for the weekend!

Just wanted to say thanks very very much for everyones help and advice !

Nice one mike pleased you got it sorted

This Morning she wouldnt start again! removed the bleed screw from the top of the filter housing, after around 8-10 turns she started, I left the screw out, it ran for around 20 seconds before any fuel came out the hole. definately air getting into the system.
Changed injector spill pipes for new ones. checked the condition of the drain plug which looked fine, made sure it was tight ensured all injector pipes were tight.
Is there any where else i should be looking?...

Check the fuel pipes that go into the tank unit, remove the round plate in the boot floor and you can see the tank unit , clean them and check for pin holes.

Tomorrow I will be checking the fuel sender unit connections, fuel sedimentor and smearing em all with some clear silicon to be safe.
And with advice from Discomania putting some PTFE on the union connections I have undone during the past week.
also a new filter to be sure. will also check the filter bracket for fractures and cracks.
