My '92 Acura fails to start sometimes. It will work fine for days, then one day it will crank but not start. Later, it will start fine. Research suggests a main relay problem except for one thing: this problem seems to have nothing to do with the heat. The first time it happened was in late summer when the day was warm but cooler than it had been in a couple weeks (Washington DC summer). The second time was in the morning of a warm but not particularly hot day. Yesterday it was cold and rainy. There have been times when it's been far more hot and I haven't had a problem. All the "bad relay" information suggests this is a hot weather problem.
Should I pursue the bad realy diagnosis anyway? Any other suggestions?
Thanks,
