Hello All, I am having an issue with my 2003 350z. I have not started the car in a few weeks because I was out of town and a bit busy when I got back, but when trying to start it the other day, the engine would not turn over at all. I would hear a click and then after letting the key fall back, the car beeps (not the horn) 3 times and then all the interior lights start flickering. I can turn the radio on and off and put the windows down, but I cannot roll them back up. Any ideas as to what is going on?

 

Charge the battery?

 

Start with charging the battery and see if that helps. If not (and the battery shows full charge), progress to checking grounds and making sure all systems are getting power.

 

As stated above ^^^, jump or roll-start and get it load-tested at AutoZone etc for free. Also, Harbor Freight has battery tenders for like $20. Worth the money!
