I know this question should be in the engine section, but since the majority of everyone comes here, I took my chances. What is the most common thing to look for when a car won't start. I'm looking at a 69 Chrysler thats being sold for $500 from a friend of mines garage. The car ran last year, but now when he tries to start it all it does is make a clicking sound. My first guess would be to start checking the starter wiring or replace it altogether. (the battery is good). What do you guys think is causing this and what do you recommend doing first? Please, any and all responses will truly be appreciated.
