HouseCallAuto 10/7/2012Toyota Camry at least does not power on the fuel pump at all until you begin cranking the engine, that is why there is no noise when the key is turned on, it's normal. Your cause here may not be fuel related at all. Determine if there is ignition spark present (yes or no on that please, don't skip) Plug in a code reader and see if any fault codes are stored. Possible broken or jumped timing belt.
HouseCallAuto 10/8/2012If you have good spark and you have good fuel pressure you have to confirm that the timing belt has not jumped by removing the timing cover and aligning the marks. You also should be plugging in a code reader to see what fault codes are stored.
