2003 CL won't start when engine is hot on hot days

I have this strange problem for a dozen times this summer. In the mornings, my car always started fine. But when I turn off a hot engine, it won't re-start. I had to pop hood every time and wait for 10-20 minutes, then I re-try and it would start fine. My battery is less than 2 yrs old, I think battery is ok.

Anyone had this problem too? what's the cause and fix? Thanks a lot!!

Two most likely causes: flaky PGM-FI relay and gummed-up Idle Air Control (IAC) valve.

Thanks, I ordered a relay unit from ebay for $30. Let's see whether it can fix this problem.

my new fuel pump relay arrived. Git it installed in 10 minutes. Only used a flat head screw driver to push relay unit from the metal bracket. Then disconnect the brown color connector from relay unit and install new one to the connector. Car starts right up but weather is not hot now, so I don't know for sure the problem is fixed until maybe next year.

If you're the experimental type, you might try re-soldering all the solder joints on the old relay and keep it as a spare.
