I started running 98 high octane unleaded and noticed one time after I shut the car off I heard the pump still running then it shut off, this only happened one time. Well unfortunately the next day after running my foxbody around town with no issues I got hit in the front passenger side and now the pump is staying on. I have checked the cut off switch in the trunk and its in the down position as it should. I believe that a wire is grounding I'm not sure, any guidance in steering me in the right direction would help thanks. Below I have attached a few pictures, and also th fuel pump is fairly new just an FYI.
