I suspect a fuel issue, I haven't changed the fuel filter or underbody pump since I've owned it and I'm curious as to whether it might be suffering from a partial blockage or weak pump which means the car is struggling to make sufficient pressure at the rail for the first start of the day.
Does that sound right, or am I barking up the wrong tree? I've had hot starting issues with the B200F in my 744 which were cured by changing the coolant temperature sensor. Could that be the cause of this issue, despite the problem being the other end of the temperature scale?
I'm keen to diagnose it properly rather than fire the parts cannon at the car as money is a bit tight at the min. Huge thanks in advance for any and all help!

i would connect a fuel pressure gauge and watch it when someone cranks it in the morning , it should go up quickly as soon as you crank , does it prime for a second or two when you put the ignition on?
