So much of what I have read here is true. I had the usual symptoms of only hard restart when "Hot". This on only hot spring/summer days and shut off at operating temperature and running short errands. Once back in the car it would just crank, and not restart after say 10-15 minutes.

I found the answer after reading the psotings here and visiting the wrecking yard. Avoid any OEM main relays if possible, but it is a great placd to start.

Once replaced it runs smoother, and starts during all conditions.

It is by far the most prone and cost effective place to start.

Hello, Ron!

I had to move your post above from Introductions to a more appropriate topic area. The Introductions topic area is only for people to introduce themselves. Any other comments or questions that a person has should be placed in the appropriate topic area to which it refers. This site doesn't operate the same way that a chat room does, and if someone doesn't place a post in the appropriate category and/or thread, it's likely that whoever it is directed toward may never see it. Thanks!

Can you let me know where is a main relay on honda civic dx 1990. Thank you

tomvu, this will help:
