my 2002 chrysler town and country wont start,

I think you need to find a local mechanic. If you are stranded away from home, you don't have tools and without more information it is very hard to say what it could be.

what kind of information can be helpful to try and see if it can be fixed

I can only say it is probably a lack of spark or fuel. Which one is impossible to say without more information. Did the check engine light come on? If so you need to get the code read.

all the lights come on but dont stay on

If you buy a can of starter fluid and spray a 2 or 3 second blast into the intake of the engine and it starts and runs for a couple of seconds then you know it is a fuel delivery problem. You can access the air cleaner without tools probably. Open it up and spray the fluid into the tube leading to the engine.

ok ill try that thanks for helping

i know thanks... im just trying to see if i can try to do something to make it run. its the first time this ever happened and it was running very well when i parked ... but i will see what i can do thanks

Ok thank God it got fixed it was actually a loose cable near the break pedals ... Car already running Thanks

I know your questions old but what kind of cable was it?
