1990 accord some time will start and some time won't crank no start

[neon01]

Hello I'm having trobel with my 1990 accord lx lately it has started acting up. The car will run great but when I shut it off it will crank but not start. I have pulled the s light code and I got codes 2,3,7,8,14,1 in this order.i found another thread with this same but the other thread said his would not start at all my will start and drive normal the when I shut it of sometime it will start and some times it won't can it be that the main relay is bad. If any one can help pleas mesege me.

It sounds most likely to be the main relay.
Does it seem to correspond with the temperature, i.e. does it start and run more when it's cold vs. when it's warm/hot?

As for your trouble codes, they are most likely unrelated to the not starting issue.

That many tcu error codes usually indicates a faulty tcu. That can also apparently cause a starting issue (why, I don't know.) repair or replace the tcu, and see if things get better.

Also, please post in the correct section in the future.

This problem only hapens when the car runs for more than 1 hour or when my car reches operating tempiture. After i run the car in those conditions and then turne off my car it wont start. In rigard to the other post i tought it was the tcu but when i read the thread that some one hade the same problem on this foream. His fix was that he hade forgaten a fuse for the maine relay and ecu. I just wanted to know if it could be the relay thats going out

Good luck to you.

Most likely is the main relay. 2nd in line might be the ignition control module inside the distributor (this can be replaced without replacing the entire distributor).
