My car is hard to start whether cold or hot; I have checked fuel pump, idle air valve, mass air flow, battery power, etc.

Hello my name is Dave.
There are quite a few possibilities for your symptoms. My first question is how long has it been doing this? Is it possible you got some bad gas or have you had this problem for more than one tank from more than one store? Another question I have is do you have a check engine light on and if it is have you had the code pulled? If you don'y have a code I would expect one to be triggered if the problem persists. I would recommend have the car scanned for codes even if the MIL isn't on at this time because sometimes there will be pending codes for a problem the ECU perceives as a minor or intermittent problem. If you can get it scanned and let us know the results that would be very helpful in helping us diagnose a probable cause for your issue. Look forward to hearing back from you with the results soon and thank you for using 2CarPros.

It takes a while to get it to start and I worry because there is only 6,000 miles on the motor.
