Car when go to start nothing no dash lights like battery is dead if keep ignition on on it will all of a sudden all lights come on and starts up but rough idle at first

Hands on testing and inspection of related components is needed. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
