I'm concerned now after this happened to me 3 times this week. If I park my car after driving it for sometime and then re-start it, it won't start. I would turn the key and it would kick over then suddely it would stutter then turn off. The only way for me too keep it running after like the fourth try is actually pressing on the gas pedal but then I hear a loud thump sound coming from the engine. I checked all connections and seems fine. My thinking it could be the fuel filter or dirty injectors or possibly I need to change the timing belt. I have about 111K. Can someone please advise me on what to check for....Thank you
