Just wondering if any one can tell me what's wrong, my 1982 Sierra ute won't start on the key, turns over but won't fire, but will push start no worries.

Have you tried a new battery or a jump start? It might be turning over, but just not fast enough to fire. Cold weather sees the chemical reactions happening a bit slower in the battery, so a battery that might be adequate in warm weather struggling when its cooler.

Push starting might see it hit TDC with with a bit more grunt behind it than the tired battery can supply, so you get better compression, a better spark and better chance of it firing up.
