I replaced the battery and cables about 2 months ago. Today, when I turn the key, the D4 light on the gear selector comes on for a few seconds and the car won't start. I could jump it off, but then later the same thing happens. Is the D4 some kind of code for what is wrong?
Battery and cables are new, but it won't start. on 1995 Honda Odyssey

If you are trying to start your Honda and you are sure it is Park and your D4 light comes on, it sounds like your Neutral Safety Switch is out of alignment or is defective. Let me explain. Your car is designed to only start in Park and Neutral as a safety feature. This is so you can't start it in gear. Starting a car in gear is dangerous because it can run some one over, so all cars are designed not to start when in gear.
