There's times that my car will start right up and I will drive it down the road turn it off in 5 minutes later it won't start it acts like it's dead but I know it's not dead. I just bought the battery like 2 months ago but when you go to put the jumper cables on the posts to jump it it starts too quick for it to be a dead battery, and like right now I came to the store and drove here perfectly fine it started up at my house and now I can get anything.

Hello,

Just to clarify you are unable to start it now? Even with a jump?

If you are unable to jump start it, then one of the most common cause for starting issues like this is a faulty coolant temperature sensor.
The sensor can have too much internal resistance and could be sending signal to the ECM that the engine is 'too hot' to start.

I have attached the coolant temperature sensor diagnostics for your reference. You will need a multimeter to do the testing.

Please let me know what else you are experiencing.
Thank you.
