Ford Excursion High Pressure Oil Pump May Fail and Cause "No Start" Condition
Ford Excursion Problem
Engines Affected: 6.0L V8 Diesel Turbo, 7.3L V8 Diesel Turbo
Average Mileage: 206,000 mi (137,000 mi - 285,000 mi)
I had a high pressure oil pump supposedly installed in my 359 7.3 turbo diesel in L.A. and it went out in Gallup N.M. Another pump was installed and when I picked up the truck the mechanic said that the #5 and #8 cylinders were not firing. It idled roughly but after initial starting it semed to run alright. I made it to Oklahoma City and noted that I had to put 1/2 qt of oil at each fuel stop. I was continuing to Tenn. and in Conway, Ar. I had to get a tow into Smith Ford. After checking the service mge told me that I needed a new engine and that the #8 and #5 cylinders were not operating. He said I "MIGHT" Make it to my destination if I continued to check and keep the oil level full. I didn't make and had to store the truck in a yard 50 miles west of Memphis. Was this engine failure due to the high pressure pump initially failing in Gallujp, N.M.????
