My 1993 dodge dakota 3.9l v6 was dead after a day at the track with the running lights left on. When my buddies tried to jump it they crossed the cables (positive to negative) and now the truck won’t start. When the key is turned there’s no lights, so dash sound, nothing. We’ve replaced the starter and ecm rn and checked the cables between battery and starter and they all had current flow. Basically we’re wondering what the next thing we should check on is?

 

You are losing power somewhere. Check main fuses first. I think there are also fusible links in there....
