OK so the stupid boyfreind would be myself. After removing the cylinder head there was no damage to the valves or the pistons and there were no marks to suggest that any contact had been made.

Whilst I had the head off I replaced ALL the valves. When I took the old ones out i checked that they all moved freely and were seated properly when closed and they did. But anyway I put the new ones in and re assembled it all with new gaskets etc. everything by the book.

The timing belt was replaced again with both the crank and the cam at TDC. I turned the engine by hand about 5 times and there were no knocks and it didn't take too much effort to turn it over (just the lumpy resistance from the valve springs)

Anyway, the car is all back in one peice everything where it was I used photos to make sure and it still doesn't start! What could possibly be wrong?

WHERE I AM AT NOW is I have taken the rocker cover back off to check the the valves are opening and closing at the correct time but I dont know exactly where they are supposed to open or close so I wrote down how many degrees past TDC the valves for cylinder 1 (nearest the timing belt) open and close. See below:

Exhaust valve starts to open 100 degrees past TDC
Exhaust valvle fully open 135 degrees past TDC
Exhaust valve shuts 180 degrees past TDC
Inlet valve starts to open 190 degrees past TDC
Inlet valve fully open 250 degrees past TDC
Inlet valve shuts 280 degrees past TDC

I can also confirm that the piston in cylinder one is at the top of its stroke when the crank is at TDC (as it should be).

THANKS IN ADVANCE FOR ANY HELP! I REALLY NEED IT I CANT AFFORD TO PAY A MECHANIC! SORRY ABOUT THE LONG REPLY!
