Ok, lets take this from the top. I have a 97 f250 diesel. In mid may mine did the same thing. It's either one of two things. You have under valve cover harnesses (uvc). They slide in under your valve covers, you will see two wiring harnesses on the outside of the valve cover gaskets on either side of the block. Ok, it IS possible one of these slipped out of place and killed two of your injectors, causing the horrible running/ low idle/no power/ sounds like the truck is going to stall symptoms. The easiest way to check that is to unplug the wires while the truck is running and see if it kills the engine, if it doesen't unplug the other one on the same side of the valve cover. If both of these don't cause any change then you have a bigger problem, the IDM (Injector drive module).
FAIR WARNING: When you unplug the wires with the truck on it is extremely dangerous, it is 110 volt feed. It can kill you.
OK, the IDM is a silver box, 8"x10" approx dimensions, located on the driver side under the hood, over top the front tire. If you take the wires you unplugged and take a multi meter to them and they are dead, you have a bad IDM. This was the case with my truck. Ford designed the IDM to have a hole in the side to allow condensation to escape from it, unfortunately, this allows water inside and will short out resistors and practically kill half of your engine. Buy a new IDM on ebay for about $380. It takes 5 minuts to put it in.
I hope this helps you out man.

SOURCE: Changed Fuel Filter with full service but engine not turning on
Hi a1999 E 320 CDI started with the help of a push of the fuel pedal for the first time after replacing fuel and oil filter and wouldn't start for the next few times. And I discovered the new fuel filter didn't fit properly so I put back the previous one BUT still it won't start. Thank u and much appreciated if any quick response
