Summertime Blues

[OKHawk]

1990 Acura Integra LS starts great in cool weather. Once the temperature outside climbs over 70 or so and sitting in direct sunlight it acts like its not getting any fuel. Usually after many attempts and up to 20 minutes later it will start. On a few occasions it never did before the battery went down. The next morning it fired right up. If its under cover out of the sunlight the temperature outside has to be quite a bit higher.
Very frustrating.

sound like a bad fuel main relay... They do this in hot weather... I have an extra one that I repaired and tested and you can have it for $20 shipped. They are about $50 from an auto parts store. Let me know if you want it...

Here's one way you know if its the fuel main relay... When it does not crank, is the c/e light still lit up on the dash? Then, when it does crank, is the c/e off? If so, its a bad main relay... Very common problem on hondas.
