I have a list.....
These cars were ment to be DRIVEN....they don't sit well and when they sit they become more tempermental.

1. Check coil.
2. Check cap & rotor
3. How old are the wires?
4. How old is the battery?
5. When you try to start does the starter always engage or do you get clicks or does nothing happen?
6. When it does start any colored smoke from back end?
