Cold start issues

 Hi Can anybody help me with trouble shooting a cold start issue I have on my 2001 996 C4. 
When winter draws in and mornings get colder I have to turn the car over increasingly more times before it starts. 
Last year it was a max of three times before starting this year I am up to five times before it starts. I have had a new MAF fitted and a couple of other sensors recommended by the Porsche garage I use, but issue still persists. When the car is warm it starts first time every time. 
I drive it regularly, battery has been checked and is strong. 
Any advice gratefully received 
many thanks.

Hi Richard
Not sure what you have had replaced but the Crankshaft Sensor can cause starting issues but usually when hot.
If it does start the I wonder if its fuel pressure related?
Good luck

Thanks Andy
i checked the invoices and the crank sensor is one that has been replaced. I will do a bit of digging on the fuel pressure question.
