Checked the timing belt? One of my friends had a similar issue, on a fresh build. The car would idle, but, it was an absolute ******* pig to try and drive.
Inlet and exhaust cams were 180 degrees out on the nearside head. Suprised it ran at all.
Checked the coil packs? You make no mention of whether they have been replaced. They break down as they get older, the heat from the heads makes them brittle and crack under the rubber boot.
Just another couple of ideas for you to look at.

I can't remember how long the wires on the plugs are. IIRC it is possible to plug one of the injectors into the cam sensor wire though.
