Friend's 2002 Camry is having difficulty starting in the afternoons during the hot summer sun in southern california. The starter turns over ok, but the engine has difficulty starting. She usually remidies it by stepping on the gas slightly while starting the car, which pretty much starts it. It starts normally in the morning. The car is not ever parked in garage. I suspect needing the slightly step on the gas pedal suggests its a fuel issue - maybe some techron in the fuel may help clogged injectors? although why is it fine first thing in the morning? leaking injectors also doesnt make sense - why is it ok in the morning? if it were plug/distributer or battery related, then why would stepping on the gas help? Wish i could give you more info, but this is all I got over the phone. Just looking for some feedback before I get a chance to check out the car later.
