Now, leaving work, only 2 times on the glow plugs and it started right off, without hesitation like the problem never happened.

Bad fuel? I use the same fuel from the same petrol station for along time now without any problems.
They say at the balcony that it is additivated diesel and cheaper than regular:jaw:.
The company site has a product "datasheet" that explains it is a 7% biodiesel 93% Diesel and some marketing addictive. Strange thing is that every value of the charts between regular diesel and this "special" one, is exactly the same.
I have filled the tank with regular diesel and had about 14 liter = 3.0795682 Imperial gallons.
I had negative "ground" problem. All the crimped terminals were isolated from the cable. I sorted all that out and problems went away. The head can't be isolated from the block can it? All that head bolts...
I'm glad is weekend
