weather

Hi, My 2002 Protege5 won't start on hot / warm weather, especially if directly exposed to sun. It doesn't crank at all and no clicking. The fan blower, wiper and sun roof doesn't work as well. Rest work fine. I have to wait till weather cools down in evening and it starts like charm.. Not sure...

My temperature gauge on Sport Ed. always reads a few degrees (+5-10) more than local weather casts. Normal?
