Colder mornings the glowplug light comes on only for couple seconds
and lots of cranking to start, lots of smoke due unburned fuel. Rest
of day it is warmer & starts OK. Replaced coolant temp sensor thing
that it sent the engine temp but no change. If I turn key on/off six
times alowing glowplug warmup each time start is OK. Any suggestion
where I could go next by myself? (not to a repair shop)

If glow plugs aren't the problem, then check glow control unit or
connections to the temp sensor.
