shortage?

[punchpipe]

my gages on my 95 grand prix, temp and fuel, fluctuates consistently.
my temp gage stays at 190 then goes to 220 and climbs until the fan comes on it doesn't even stay stable at the 210 mark like it used to.
either above or below the normal. my fuel gage just bounces around.
when idling its stable, but once i start driving it fluctuates. is there any way to check for a short. I checked the fuses they are ok. Is there a
relay or bad fusible link that might cause my gages to bounce like this?

my other question is when i turn my key to start the car sometimes it starts on the first try sometimes the tenth try. Basically whenever it wants to start. i had the battery replaced, starter,and the alternator. it just clicks clicks clicks! PLEASE HELP!
