1991 Toyota Tercel starting problem

It will start fine in the morning, I take it to work and when I am ready to return home 8 hrs later it will not start. The next morning it starts just fine. The engine turns, plenty of battery power. No spark at the plug. It was in the 85-90 last night. Raining and wet does not make a difference. I will drive short distances maybe 10 minutes and will start ok, 30-40 minutes to work and then there’s my problem.

This isn’t something one can just say, “Change part so and so, and all will be well”. No, the ignition (spark) system needs to be tested. Here is a link to tell you a little about the ignition system: http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c1528006ef76
