02 f250 7.3 runs for 20 seconds and then dies
My 2002 f250 7.3 diesel will start and then runs for 20 seconds and then dies. I thought it was the fuel filter so I replaced it. This caused no change. Then I thought it might be the fuel pump so I checked the fuel bowl the filter goes in after the truck died and it is full of fuel and seamed to be pressurized. The batteries are good. What could cause the truck to run for 20 seconds and then loose power and die?
This has been getting worse over the last week. It started by loosing power if I did not let the truck idle for ten minutes before driving (I started using fuel additive at this point). Once the truck was done idling it would run fine the rest of the day and I would start the process over the next day. You should know I live in AZ and it is 70 degrees out side. Then it got harder and harder to get running until today It will not run more than 20 seconds at a time.
