My Accord has begun give me problems when trying to start. It doesn't happen all of the time and seems to happen most when it has been sitting outside in the heat. When turn the ignition, the starter runs and the engine cranks but won't catch. It's like it's not getting gas. Any ideas?

Try replacing the main relay, located left of steering column. Turning the ignition key on and off will help you locate the main relay, by allowing you to hear and feel it "click." Main relays often have 7 wires going to them.

It's common for main relays to act up during the summer heat, when cold solder joints on the circuit board separate and prevent the fuel pump from running.
