The car starts, rattling noise comes from the motor and the car quits when taking foot off the gas peddle.

I had the same problem along with a rough idle and found out it was my EVAP canister.

Is the car flashing any codes. I would look for fuel issues possibly fuel filter, injectors etc. Because these items are easier to check. Otherwise it sounds as if the timing is off on the car. If the Hydraulic tensioner is not replaced this could cause the belt to jump teeth as well. PRETTY SURE YOUR TIMING IS STILL OFF

Try the ignition switch,
For the Crank sensor there is a small metal disc that mounts behind the sensor if that is cracked or dammaged or installed backwards you will get same results as if it wasn't Make sure the timing marks line up on your timing belt. www.kiatechinfo.com

Although is could be a fuel filter, it could also be a fouled spark plug, or a bad spark plug wire. Once you've ruled these things out, the problem could be the TPS (throttle position sensor). This controls your idling speed under all conditions. A faulty TPS will usually idle fine when the engine is cold but once warm, will tend to sputter and in some cases, stall.
