Car wouldn't start when cold

'92 Nissan Sentra GXE AT

When it's cold (like in winter on Tahoe) it takes about 2-3 min. of cranking (not good for the battery, yeah?) and pumping gas pedal (Useless?) before it starts and afterwards works just fine. And then again next morning. In warm climate (Bay area) it starts always no problems. What should I take care of?

Thank you, guys!

You should over pump the gas pedal, when you feel the car catch, then pump more. Try new spark plugs and spray some carb cleaner to your choke. Usually in your case it's a sticky choke. Maybe a future fuel line issue. When was the last time your gas filter was replaced?.

Thanks a lot for a reply!
Fuel filter - year ago, (~10K), I will do TB cleaning in 3K, hope it will take care of that.c Oh man I hope it's not fuel lines :( That would be messy :(
