It only makes a clicking sound when i hit start

No joke that grounds can cause problems elsewhere.

I had installed new battery terminals on my wife's car becuase the flimsy little factory ones had almost wasted away. In doing so, I had to replace the main ground wire. After about 2000 miles it had come ever so slightly loose and was causing several problems.

For one, it would turn over the starter but didn't supply enough juice to supply spark.
Then, if the car ever did start, it would occasionaly miss and sometimes just totally turn off. (Yeah it was scary)
I had done several different things looking for problems. I replaced a leaky valve cover gasket (which needed to be done anyway), installed new plugs and wires, kept the terminals shiny clean. Then, one day, I found the slightly loose ground bolt and tightened it. Now, the car has ran like a champ ever since.

All of this, and every other electrical component would work just fine.
