I got my spark plugs done a few days ago. Thursday I went to go start it up and it was dead. Brand new Interstate battery it’s been working great. Still went to go get my jumper pack and as I was about to pop the hood all the lights came on and I started it. Went to go start again today and it was dead with the same feint flickers on the dash. Told my brother just wait a few minutes and I was right it turned itself on like the last time. What could it be?
