Just bought a '90 Accord off my Dad two months ago. He had the distributor replaced just a month or so before he sold it to me. Last weekend, the wife was heading to work and it just shut off on her. The Check Engine Light came on. A few minutes later it started for her. When I have been able to get it running, it shuts off after 20-45 minutes. It would then take a while before it would start up again. Now it won't start at all. The CEL is flashing code 14 for the IAC valve. That's $275 at the parts stores so I replaced it with one from the local parts yard. Still won't start. Still flashes code 14. I also replaced the main relay thinking that was it. Still won't start and is still flashing code 14. Any one have any ideas? Thanks!

First thing to do is verify what is missing spark or fuel.

 

I had the same kind of problem, Make sure you have fuel and if no spark, I replaced the Main relay under the dash and that fixed it. I read somewher that they become intermited and just crap out on ya.
