So i have a 93 del sol d16z6 swap with a battery conversion to the trunk. I pulled up to the gas station today, filled up, and when i go to turn it on it has no power. Nothing is turning on, not even the interior lights. I tried jumping it at first, did nothing, then i checked the fuses, everything checked out and the battery tested fine but still nothing. Any ideas?

 

Bad ground somewhere...My eh6 does that...i open and slam the hood, then it starts...who knows
