Hey guys i wanted to ask for some advice before i start crawling over the car tomorrow. Heres what happend

Car ran perfect, no problems starting what so ever. Parked the car, shut it off and went to start it 2 minuets later. I had full lights and the second i pushed start all the dash lights died and didnt even turn over. I tried to jump it, when i charged it the dash lights came on, but the car would only turn over once and the car wouldnt start, all the lights went dim. I was able to bump start it, got home shut it off and went to turn it back on. Again full dash lights, pressed start and everything died.

Cliff notes.
-car was fine
-pressed start everything died, didnt turn over
-couldnt jump it, would only turn over once wouldnt start
-bump started it, got home tried to fire it and everything died

I checked the battery terminals and theyre good, so is the ground and the battery is only a couple years old. Tomorrow ill test the battery and alternator, maybe the starter to if i have to. But if anyone has had this problem before please chime in.

Thanks in advance

Check all fuses

 

brad that sounds like a loose battery terminal if the terminals are tight at the battery then check at the starter solenoid or the ground wire something is loose or has a bad connection hope this helps
