Won’t start

[August07]

Was working on interior for about 3 weeks and didnt get to run the mustang much. Today I tried to start it but i got nothing, sounds like the starter dragging then almost catching then not starting, I’ve tried giving it gas while starting it but that was fruitless. I ordered a battery tester, which arrives tomorrow, but i’m still at a loss as to why it won’t start now

Was the battery connected while you were doing the interior work? If the doors, glove box, etc. were open your battery may be run down. May just need to charge it up.
