Help!!!
I have a 5ltr NC11 Fairlane that won't start. I moved it about 100 metres and turned it off then about 15 mins later it wouldn't start. I left it for a few days and it started and I moved it again and it hasn't started since. There is power at the coil HT lead but no spark at the plugs. I replaced the ecu and that hasn't helped, also replaced distributor cap and rotor. Can anyone help me please.

"There is power at the coil HT lead but no spark at the plugs" -

are you saying that you have spark at "HT" king terminal of coil or are you saying you have ignition feed at the low tension circuit of the coil -
if you have spark at coil try new coil lead (use one of your plug leads just for a test)
if low tension check for ignition positive when cranking and negative pulse on other wire (put a test light across both these connections- should flash while cranking) - if flashing possible coil fault

is distributor turning ??

Thanks for that. I have put in a new coil and it still won't start.
I think it may be the dissy?
I have power to the dissy from the coil but still no spark.

I forgot to say the dissy is turning.
