Hi,i was driving when my vectra lost power,then picked up again,it did this several times.Then all power went speedo dropped dash went off.When i try to start it now engine wont even turn over,but can bump start it.Could it be battery problems,tryed to charge battery,went to green then took charger of left for afew hours and went straight back to red,would battery cause this problem ????
