In the summer when my engine was hot and I would attempt to start it after being shut down for a short while I would have the same problem as most guys and the engine wouldn't start. The solution was to hold the gas pedal down or you could turn the key on to let the fuel pump fill the fuel rail for a minute before attempting to start the car and even then it didn't start like it should.
This spring I changed my spark plugs even though the car only has 27,000 miles on it. I used Autolite double platinum instead of the stock single platinum and not once, this summer, have I had a problem starting my car and it has been around 90 degrees most every day for the last month. I don't know what the technical answer might be but I don't have the hot start problem anymore.
I figure, that if your changing plugs it might be worth the little extra money for the double platinum.
