05 6.0 VERY hard start cold
Hi all. Its been a while since I have had to post here. My 05 F450, 134K miles, would not start after sitting about 7 hrs. I did replace the fuel pump and the short harness. It took a while to start but ran well that night going home. Now it is very hard to start either cold or, if it has been sitting during a work day. When it does start, I have to sit and feather the throttle til it warms up some. It will start if plugged in overnight but, runs rough till it warms up. I do all my filters with Motorcraft on a regular basis. In the past I have replaced...19 fuel injectors, Hi-pop, FICM, EGR cooler kit and OEM oil cooler, fuel pressure reg update kit. I do really like this truck and it does what I want and more. It has been over a year since the last problem, It is just hard to keep this up. What could be wrong now??? Your help and advise is always welcome.
