I would replace the temp sensor. This will tell the fan to turn off.

IS IT AUTO OR MANUAL?

can be the first signs of the cam sensor failing.

Look for a foreign object in the fuel tank. I once had a carbon receipt plug the fuel pick up tube. You could be getting water in the fuel too.

With the information you've given, I would be checking the battery and the battery cables. This time of year batteries are known to give up the ghost. But oxidation on the battery cable connections would be high on my suspect list. Since you seem to be unfamiliar with automotive maintenance, I would disconnect the battery and place it on slow charge. Inspect and clean the battery cables. After at least 3 hours, reinstall the battery, positive (+) cable first, negative (-) cable last. Turn the key. Good luck.

i would try jump starting the vehicle first and get idea if battery is dead before trying anything else. take battery to auto store and test if good, check battery connections are they all crusty, clean with vinegar and brush clean and reconnect. those are the first things i would check before going any farther.
