    I have a 2012 toyota tundra 5.7 platinum. The first turn of the key it won't start, the second time of turning the key it will start towards the end. And barely start. But then after that it runs fine. I could drive it for 5 minutes and it will start on the first crank after that. Any information will be helpful. All electrical checks out battery, starter, alternator all have been checked and are good.. I think it's something with fuel to air ratio.??

    Search this site for hard starting with 5.7 flex fuel. There’s a tsb to address the issue.
