Hello all, newbie here. My 2014 Titan fires up and runs perfectly in the mornings and in the evenings. However, its been really hot lately and mid-day it wont start (Arizona, already hit 100+ degrees). It just turns over, it will take 4 or 5 attempts before i can get it to start. Sometimes it wont start at all. I had the fuel pump replaced last week, and that didnt resolve the issue. Im back to square one. Again i go out at night when temps are cool and it fires up no problem. Anybody have similar issue or know where i can start?
