i took my 92 integra to speedes to get it checked because my car turnes off when it sits in the sun for a long time. when my car is sitting in the sun for hours and the inside of the car gets hot, thats when it turns on for about 1 sec and then turns off acting like its getting no fuel to the egnition or wharever its suposed to go to to start the engine, obviously i dont know about cars. then i would try to turn it on but it just wont start until i put the car in the shade and let it sit a little, after that it starts with no problem, and the car runs perfect, u wouldn't even be able to tell that something is wrong with the car. they already ran the diagnostic test and some kind of fuel pressure sensore came on. can it be the fuel pump that is causing my car to loose fuel pressure in the heat?
