My rs turbo has real issues starting when engine has some temperature. The car will fire first time when stone cold but as soon as it has some running temp it takes a while to fire. Its not the starter motor as this is easily turning the engine. I find the best way to get the car to fire is to have the accelerator pushed to the floor then turn the car over this normally works. Could this be a sensor or poor fuel pressure?

 

Check your CO, and for any air leaks, then check the igntion timing.

is this the CO sensor that could be on its way out?
