I have a 83 280zx non turbo. I was having issues with the accs not coming on when I started car but would come on when I started driving. A day later I was driving on interstate when the car sudden started losing power it eventually shut completely down. When I started looking at the problem I found the fusible wire box had caught fire. Also had a burnt smell coming from inside of car under dash area. I got a replacement box hooked it up now everything inside comes on but not getting power to fuel pump. When I direct wire the fuel pump to the battery the pump comes on with plenty of pressure. But car will not start. Is there any more test I can run to figure out problem? Anybody know whats wrong? Please help
