Help someone! I have a 92 acura integra GS. Started out with the car not starting when days are hot and car sits out in the sun. Problem got worst when it started just shutting off after driving for a while. Took it to the shop and was told it was a faulty fuel pump (low pressure). Changed fuel pump, but car had trouble starting, then I resoldered the fuel pump main relay and it started and gave me no more shutting off problems, but I still have problems on hot days when car sits in the sun. Starts up fine when it is cool, but when it is hot it just won't start or it will start and shut off right away. Sensors? Fuel system? Starter? Cables? Fuel Injectors? No one can tell me what it is? Any ideas suggestion?
