Car intermitently won't start - Electrical fault?

[Hughesie90]

Hi Guys,

 

Just replaced my battery on 350z a week or two ago as last one died. I've been driving around fine over the last week or so, then this morning I went to start,

dash lights came on, and when I turned the ignition it was almost like the battery was flat it would splutter, and all the dash lights would go off, I'd remove key,

check the battery was tightly connected and then I'd sit back in the car and it would start first time, I'm baffled, any ideas?

Sounds as if the battery leads were loose to be honest

Battery connections or engine grounding leads.

 

Starter connections.

 

Alternator issues.

 

Faulty new battery.

 

etc etc etc.
