I have a 92 accord and it sat for two months! Then it would not start! I have changed the fuel relay, filter , battery, and cleaned the system! It wii start and run fine as long as it it in drive or Reverse! But when in park or neutral it will die? Any ideas? I know it has to be something simple since I can drive it at the speed limit and it is fine!!
