2000 Courier TD starting problems

[workhorse]

I have just bought a 2000 2.5 TD with 100K on the clock. A good service history every 20K. Had problems kicking over at the dealers, thought flat battery from sitting in the yard. On pick up started first time (thanks to new battery) drove home like a dream. Had an empty fuel tank so I popped in $25 worth of diesel.
So this morning hoping to drive home out of Sydney the ute wouldn't start. Lots of go in the battery but no start. The water in fuel indicator was on so I replaced the fuel filter (full of water and crap) bled the system, still no start. Replaced the glow plugs, rebled the system, still no start. Spoke to a few Ford mechanics and was told I've done everything right.
Any help greatly appreciated here.
Have I bought a lemon or is it something simple.

Problem Solved.
After hours of internet searches on all the applicable forums, calls to the helpful people at Taree Ford, and finally the boys at ARB St Peters, the problem was in the glow plug wiring. A problem overlooked by the prior owner and mechanics, was the circuit through the glow plugs falsley indicated the plugs were being heated for the required time, but in fact the sensor was not working so no current to the glow plug rail. A wire from the positive terminal to the glow plug rail for about 10 seconds and she kicked first go. So now the hunt to isolate the sensor or relay, but in the meantime the wire gets me going first thing in the morning.
Many thanks
Must say got a few replies on the ford forum regarding assistance
