1994 F250 7.3L Diesel VIN code F, truck idles rough sometimes

Resolved Question:

1994 F250 7.3L Diesel VIN code F, truck idles rough sometimes after depressing clutch pedal, not a constant issue though, but the previous owner stated that its has shut down while driving but fires right back up, was thinking fuel pump and or injection pressure regulator, any ideas would be most helpful, thanks

Hi JACUSTOMER-i4wljkux-.

 

 

 

 

Thank you for asking your question on JustAnswer. The engine may stall when coming to a stop or after clutch disengagement. This may be caused by one or more of the following:

  • System-related conditions identified using the Diesel Engine Performance Chart,
  • Fuel injection pump contamination or
  • Use of low lubricity fuel.

the previous owner says it would sometimes shut down while at cruising speeds not just coming to an idle, the truck starts fine everytime, i plan on changing the fuel filter, fuel pump and possibly the injection pressure regulator, any other ideas
