Volvo 850 hard to start when cold

[Adam]

My 1996 Volvo 850 wagon does not want to start at all in the morning,
however when I plug in the block heater for half an hour it starts first
shot and restarts fine all day. I changed the plugs, distributor, rotor
and air filter. The car runs smooth, but this did not fix the starting
problem. Any ideas?

I had a similar case and getting a new battery helped.
