My truck has just started a deal when you drive it and it sits for hr or so it don't want to start when it's hot.Starts real good in morning but seems after it gets hot it's hard to start when it sits.Motor has 135,000 on it and am wondering if the stock fuel pump is going away as IP and other fuel stuff was replaced 9000 miles ago?Also today when it wouldn't start I opened the filter bleed and nothing came out?I came home after finally getting it to start and shut off the motor and it restarted fine...What's going on as I figure it's a fuel issue?
