The most likely problem is a failed safety switch in the transmission. It will only allow the engine to turn over when in "neutral", or "Park". Next time it happens try moving the transmission selector through the full range of travel a couple of times. If this cures the problem, you may need new switch.

clean the throttle plate

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.

Car no start problem is sometimes very difficult to confirm. You try all the possible things, but still you get no fault and problem is still the same.--------
In that case, you need to check few things individually.
Check the spark,the battery,the crank, the fuel and other most possible parts. Click this link below for more details:-- http://howtobyme.blogspot.com/2011/10/car-troubleshooting-tips.html

That would be the oil filter adapter gasket. You might be able to find it t your local auto parts store and for sure at the dealer.

check the ignition switch

try doing a colling system flush ,if that doesnt help replace the waterpump!!!
