Like a phoenix from the ashes she was reborn.
Well, the TDi is in and running!!
She started for the first time this afternoon. Would have been yesterday morning had it not been for a bad earth

. I promptly blamed the batteries and put them on charge overnight.
She still wouldn't start today so a quick call to the short person identified (with the help of a multimeter - Yes! I used it myself!) an earth fault. A quick go with the emery paper and she fired up right away.
A few jobs left to do - a custom hydraulic hose for the gearbox oil cooler leaked from new

so I need to get that replaced. Got a spare on for now. Also need to sort out the fuel gauge sender.
[Ashamed mode] Need a new water pump [/ashamed] Skinflint here decided to use the existing pump as an attempt to save money. Of course it leaks out of the weephole.

So thank you to all who said change it, you were all correct and I was wrong. Bugger.
Oh, and I need an MOT.
All should be well for the weekend. Keep your fingers crossed!
Big thanks to Chris, Mark, Jonathan and Matt for the help, encouragement

and advice.
I am completely shattered and am off to work tomorrow for a rest!
