1997 hyundai accent hard to start when cold & lack of power Sign In

I have a hyundai accent 97 sohc 1.5 in good conditions. 120 000 km but I have problems to start when the engine is cold, but warm weather outside. Starter runs well but for a long time and hesitations when the engine starts. battery, genuine sparks plugs & wires and coils are ok. I checked intake air temperature and seems to be ok and engine coolant temperature but not sure if ok. the resistance vary between 1600 to 3200 (IAT + ECT when cold) and 200 to 300 ECT when engine hot at 68F. I also checked my mass air flow sensor and it said .260 volt at idle and .235 at 3000 rpm. the specs mentionned .7 to 1.1 volt idle and 1.3 to 2.0 at 3000 rpm. maybe I did something wrong? positive lead on terminal 1 and negative to ground. someone to help please, thanks

ignition coil primary windings 1.1 ohm (terminal 3-2 and 3-1) not in the range at 68F ???
secondary windings 1-4 is 11.84 Kohms and 3-2 is 12.36 Kohms
