Default 91 Honda Accord Starting Problems?

I have a 91 Honda Accord that wont start at random times, but once it starts it will go forever. Its usually after i drive it a bit and after i wait 15 or so minutes it will start right back up. Any suggestions?

The most common cause of this problem is a bad "main" relay. This is also called the fuel pump relay. It is located in the dashboard, near where the left air vent is located. You might try this experiment: while you have the key turned to Start and the engine is cranking but not starting, use your left hand to give a sharp whack to the dashboard above the left air vent. It might start. See source or more details about the fuel pump relay.

That vehicle is quite old and if it has a lot of original parts it could be almost anything from the ECM/main relay or the fuel pump relay or the ignition or wiring or even a bad battery.First off the connections at the battery/starter/alternator/engine block ground/ fuse box can all rot or corrode or rust even the cables/wires can rot/corrode internally.Sometimes a battery will have bad cells inside of it and once the battery sits awhile it builds up enough good cells to start the car.This means besides cleaning and checking those connections/wires/cables I've mentioned have the battery/charging system and starter tested.

Hope that helps and best of luck.By the way if that vehicle hasn't had the electrical connections/system over hauled or any of the battery/starter cables/wires changed or the grounds cleaned I'd want to start there, plus it may help that vehicle a lot to have a new main relay[part no 20413] and the fuel pump relay[ part no 19236 ] installed.What may also help is cleaning the relay socket pins/legs, spraying the relay socket connections with electronic contact cleaner/tuner spray then let it dry and put the relay back into place.Note you may want to disconnect the negative battery post whenever using such spray.
