Had my tuner mess with the tune some and he got it better but if the truck sits for less then 4 hours then it's hard to start and have to pump the gas. I did notice when truck is cold and I cycle the key on, the pressure will slightly drop and start right up, if truck is warm and I cycle the key , the pressure will slowly rise and then that's when the issue happens of long cranking
