car wont start

i got a 90 protege but it wont start, i get the clicking sound but wont start, i had the battery checked and also the alternator check. apparently they seem to be fine, it works fine for about 3 days but then it dies. does anyone have any sugestions. thanks

My roomates '94 GTO does that, only his starts. But he says that its the fuel pump. So you might want to check the fuel pump and regulator.

Have you checked your starter, that might be a cause of it not starting also.

Are your battery cables clean and in good condition?
