Cold start problem
Only when the car is cold it takes a while to turn over. Cranks, rumbles for a little then starts. When it's warm it's starts perfectly every time. I have replaced plugs, wires, tried different gas etc. still happens. No codes thrown. Any suggestions? Compression issue? Thanks.

Your explanation of the cranking issue need MORE info.
DOES IT:
Not Crank when you turn the key to CRANK?
or
Crank for an extended period of time before it actually RUNS?
or
Cranks slowly before the engine starts and runs?

Option 2: Cranks for an extended period of time before it actually starts. The crank noise sounds normal ie does not appear to be a battery or a starter issue to me. The motor sort of "skips and grumbles" before it actually starts - crank, skip, grumble, crank, then start - if that makes sense. However, if the motor is at all slightly warm, then it cranks and starts normally. Car only has 50k miles on it never been opened up, etc. and the issue only started in the last 5-8k miles. Dealer said that new plugs and cables would clear up the issue but it still remains. Once the car actually starts it runs perfectly. Thanks for the help.

I changed out the fuel filter and also got a new battery. The issue still remains. Only on bone cold start up the car flutters while cranking and has extensive crank before firing. Starts perfectly the rest of the day when warm. Any other thoughts. Thanks.

Leo, most cold start issues are associated with a faulty ECT sensor...there is a resistance vs. temperature chart you can use if you can remove it and you know your way around a multimeter !!...after the car sits overnight compare the coolant temp to the outside temperature...they should be very close !!
