hello i have a 2003 dodge neon sxt 2.0 my problem is sometimes the motor will just crank and not start. when it wont start i can leave it alone for 1 or 2 days then try again and it fires right up. any suggestions what it could be i was thinking fuel filter/fuel preasure regulator it did throw a evap code so theres probly a leak somewhere but i dont think that would cause it not to start. thanks for any help

i did new wires and spark plugs recently 6months ago
