Hello new to this forum
2008 XLT 4.0 I have replaced the CPU and the wiring harness after heater valve breaking and some subsequent over heating issues. Currently the truck cranks without starting most of the time if I turn the ignition to on for a couple of minutes it minutes it will start maybe rough idle for a minute or 2 then it's ok. I have also replaced the fuel pressure sensor, PCV and Fuel Pump Driver module
Any ideas?
