Vehicle Fix Fund

I am a SSgt in the Air Force and am currently deployed overseas.  Just after leaving my vehicle broke down on my parents who are caring for my two kids. We fixed part of the vehicle but we no longer have the money to fix the last problem the (pcm). I am not someone who asks for help but I am asking now as this is my families only vehicle. We need it to get groceries, go to medical appointments and get my kids to and from school.

Any and all help would be really appreciated in mt time of desperate need.
