No Spark.

Hello all. I was wondering if I could get some people's insight and advice. I recently bought a 73 318 duster. It had starting problems, and I thought i tracked it to the pickup coil. I replaced the distributor and got it starting and running again so i thought i had that licked. Anyway, its got other major problems and when i tried to get it in the garage to take the intake/valve covers off to get a look at the lifters/cam (I think i wiped a cam lobe.. there's a post about it) I couldn't get it started. There was moisture in the cap and what looked like coolant, most likely from the heater core leak that I had to bypass. I cleaned it out but there's still no spark. could coolant have done some damage in there? The ignition system has been pretty much completely replaced. Where do you think i should look next? I'm worried that I jostled some wires replacing the distributor and that's why it started working again, not because of the new distributor. I'm seriously considering cutting my losses and getting rid of the thing.
