No start

I have a 1994 Toyota camry, 131000 miles. Last year I installed a distributor because of no spark. I recently installed another distributor for no spark, the vehicle would still not start. I checked all fuses, and after a couple of days, I had to charge the battery, vehicle still has no spark. I waited a couple of days, went to the vehicle turned the ignition key and the engine started up, the vehicle ran for 3 days, then went back to the same problem, plenty of fuel, no spark, cranks, no start, can you give me an idea on what to look for? Thank you, Mike.
