Ignition fuse blow everytime i turn key to acc
 

So I go to start my 2007 Nissan maxima se this morning. It starts, the engine rumbles then dies. I go to start it again and it struggles to start with no success. I go check my fuses and my ignition fuse is blown. So I replace it with the same 15a, and boom, once again. It blows. So I try to see if it’s an electrical issue by turning the key to acc. And guess what it blows. I disconnected every electrical cable you can think of and turn the key to acc. The fuse still blows. So I check my fuel injector fuse, disconnect the fuel injector fuse, turn the key to acc and the Ignition fuse doesn’t blow. So I plug the fuel injector fuse back in and disconnect the front three injectors, the fuse blows. I haven’t disconnected the back three yet. But I’m wondering do I take it into the shop and have it checked out or can I get some help on here first. Thank you
