C230 Kompressor cold start issue..

[omahamerc]

I have 2000 C230 Kompressor, and have noticed when the temp has dropped to around 0-20 deg. F, the car cranks and cranks. It might take between 5-10 cranks at 10 sec each before cars starts. Once car starts, runs great. I am suspecting loss of fuel pressure. Once car is running, never stalls, or any lack of performance. I have read on here check the pressure regulator, the air mass meter, and the OVP. Not sure where the OVP is on this particular model, and wondered if it had one. Once the car starts, and warms up, it starts well during the day, unless left unattended for more than a few hours. I have also considered coolant temp sensor. Any help towards diagnosing this would be appreciated, took to dealer and they couldnt find anything wrong (they still wanted paid of course..lol).
