2002 Toyota 4runner vehicle must be jump started

2002 toyota 4runner

Vehicle sat for 3 months. Upon return, jump started vehicle, let it run for 3 hours. Continually started well for the day.

Now, when sitting overnight, vehicle must be jump started once, then will start for the day.

But overnight, vehicle will need another jump start…..

Put a new battery in it and make sure to clean the connections when you do. This should take care of your issue. *Note – each time you jump start a battery in a vehicle it weakens that battery. So I would replace the battery sooner than later.
