i got a problem with starting my car. When i turn the key my starter doesn't crank sometimes. I have to sit there for hella minutes turning the key over and over before it'll start cranking. Anyone know where the bad connection could be?

 

Be more specific. Does it spin over? If so, it's most likely the Main Relay. Possibly the distributor.

 

it makes like a hmm sound, sometimes it'll start cranking for half a sec then make the hmm sound

 

sounds like either a fuel pump problem, but more likely that your main relay is going out... Does it do it more when it's warm out?

 

Try cleaning your battery posts and cable ends, it sounds like they are getting dirty and losing contact. Put a bit of grease on the posts before you put the cables back on, this will help to prevent corrosion in the future and give you good electrical contact.
