do you have power to the headlights? that's a good quick indicator of the battery condition and if you have a ground. I have a load tester to check the battery condition. if its good its just a simple matter of checking to see if you power at the starter and switch. if that checks out then it may be the starter itself. there are a lot of smart guys that will be on the grounds don't worry we will get it running. no one wants to see a car parked due to problems. just get it there safe.
