another non starter (single spark from king lead)

After driving the car afew days ago it decided to all of a sudden lose power and stall, since then it hasnt started. There is only a single spark from the king lead which is orange when the ingition is turned, is there any reason why theres a weak spark and only sparks once? ive changed the coil for several ones but still no change, i also got another ECU and ignition control unit to no avail :dontknow: there is the possibility that these are knackered. so what else could it be? gonna see if i can get a 3rd ignition control unit to rule this out and ecu if possible

Could be the hall sender in the dizzy.  Used to be able to buy just the sender but i'm not sure you can anymore got a feeling you have to buy the whole dizzy.

Pulled the hall sender lead out to find it covered in oil, then took the dizzy cap off and found the rotor arm had melted 8O so im guessing the dizzy is going to need replaced.
