no spark, help please

What is your question?

I drove and parked my Mazda v6 626, an hour later it turned over strong, but wouldn't start. I've checked all the fuses, and checked the plugs. The plugs are not getting any spark. I tuned it up less than 6 months ago. I haven't pulled the distributor yet, I'm thinking it might be the Ignition module, or coil pack. Due to the plugs being covered in gas, I don't think its the cam shaft sensor, anyone know of this problem? Is it common? Everything else seems to be in working order, I get power to everything but the distributor
