Okay I have a 2011 Mazda 3s (2.5L) with 48,000 miles, and I am having a problem with starting my vehicle again after not letting it warm up completely. For example I will start my vehicle, back it out of the driveway and pull it back into the driveway not allowing it to warm up completely. I can come back 30 mins. later to start it again and it will take 3-5 seconds of cranking to get it to start or it won't at all. In that case I just re-try starting it and it will start again at that point. Normally it just starts no problem within a second. I've noticed this for about the past 2 months now, any ideas on what the problem would be?
