take the tool apart and see if motor wire is connected , they don't solder them and they weegle out of mounting hole .i had this happen on my 1/2 in impact driver and reciprocating saw . good luck
1/2 in impact wrench and 514 reciprocating saw NO solider on wire so wire weegles out of hole and the tool doesn't run , wire is really short but you can solder it on .
