Hi Craig - I'm assuming your 33 has electronic ignition? This makes it a bit more difficult to check if the coil is OK. What you need to remember is that the electronic box is just a switch to earth. If you put +12V onto the coil "+" terminal, and then briefly touch the "-" terminal to earth, the coil should produce a fat spark from the HT lead, if it is close to an earthed component (like the engine block).
If you jump a +12V live to the coil and use a flying lead to ground the coil "-" terminal, you can bypass the ignition module and the distributor, either of which may be suspect.
Hopefully it is the coil, diagnosing faults in either the ignition module or the distributor could be more tricky...
