Large problem. Ok heres the info, my sister has a 1995 Grand Prix SE with the 3100 series (3.1L V-6). It was struggling while driving so a hardcore tuneup was requested. I have done the plugs, plug wires, and thermostat, and also the pcv. Now when I try to start it, it turns over runs for a split second but almost sounds like its missing. But then after it dies, when you try to start it you head a louder click from what sounds like either a sensor or an ignition component. I have no clue as to what it is. It also sounds like it makes a beep noise when you put the key in the run (not start) position. Anyone have any bright ideas? Help me out I have to get this thing running we just got 15 inches of snow!!!

Thanks guys
