I have a 2010 1500 with the 5.7 . This issue has been going on for about 3 years and is a lot more prevalent in summer months. First start every morning is normal or it it's cool outside no issue so it doesn't seem like it's loosing prime. Most hot days It cranks for a long time and if it does start it acts like it misfires for a second. If I cycle the key it will usually start without issue,I have bypassed the fuel pump relay no change I don't believe it to be any engine sensors cause this is a new engine with all new sensors after the old one decided to rapidly disassemble itself. Has anyone had this issue and found an answer? Could the win module cause this?
