Honda Repair: 94 Accord will not allways start when warm, battery cables, intermittent problem

Question
My 1994 accord sometimes will not start when I make a short stop. The engine turns over but It will not crank. When this happens the D4 light will blink. I turn off the switch for a few minutes and if the D4 light is not blinking it will start. This has been going on for some time, but If I take it to a mechanic I am sure the problem will not raise it's ugly head. Any suggestions of some simple things to try first.

Roger:
Whenever you have an intermittent problem you run the risk of replacing things you don't need to replace. If you can leave it with a mechanic for several days they can wait for the problem to appear. Otherwise you will just spend a lot of money for nothing. I would clean the battery cables and make sure you have good contact. Sorry I can't be of more help.
