I have an 02 Envoy and need some help. I am 2 hours from home and it will not start. All lights work, battery meter reads 14 and is only 6 months old. When I attempt to start it i get a breif "rrr" and then nothing. Tried to jump start it and still does the same thing. For now i simply need to get it home and not pay a towing bill for 100 miles. Not sure if its the ignition switch or starter. Any tips, hints to tell which one it is and possibly get it started one last time to get it home.
