6.4 Powerstroke engine rough idle, now won't start
Hey guys thanks for all responses in advance I'm not quite sure what is wrong with my truck but any and all input/ advice would be greatly appreciated. This is the first diesel truck I've owned but I have driven my father's 7.3 powerstrokes/ 5.9 cummins in the past so I do know some basics. I am going to try and provide as much detail as possible right now so bare with me lol. I bought my truck with 90,900 miles and have 104,000 miles now. It's a 2010 f250 XL crew cab, 6.4 powerstroke diesel and the fx4 4x4 package. I have had absolutely zero problems out of this truck and when I purchased it had all service records up to the date I bought it at the dealership. The other day I was driving to work and came to a stop light. When the truck dropped down to idle speed it was running really rough, it felt like the whole truck was rocking back and forth. When the light turned green I gave it a little fuel and it smoothed out, I figured i just got a bad patch of fuel or something but when it dropped back down to idle speed it started doing the same exact thing. I made it all the way to work (only 1 mile down the road) as long as i gave it just a little fuel and it was above idle speed I had no problems. When I got into my parking spot at work I shut it off and tried to restart it. It would not start at all, it tried but wouldn't do it. Everyone at work said it was probably the fuel filters so I told my wife to grab the 2 filter kit and all the tools and meet me at work. I probably should have read the instructions first but I changed the filter on the engine first, (my boss told me he knew what he was doing just cycle the key on and off 3 times for 10 seconds and it'll fire right up.) Filter looked pretty clean but still wouldn't start. I went to change the filter under the truck next, and it was clogged full of crap, it looked like clay all around the filter, no idea how long it had been since someone changed this one. Changed it out and this time I followed the instructions. Cycle key 8 times for 30 seconds each and still no start. Please help any advice/opinions/past experiences with other engines or whatever would be great thanks so much guys!
