Ford 6.0 Diesel Problem I think my 6.0 is fixed after 8 tries. I have now out about 3000 miles on the last repair and everything is fine. Mileage up about 2.5 MPG to about 19.5 MPG and no stalling or bucking. Ford put a data recorder in my truck and discovered that the fuel presuure was dropping from 1200 psi down to 260 psi when the unit acted up. They replaced the sensor and the connector. The mechanic said he thought the connector was the culprit as several of the pins were suspect. I'm happy again.
