Re: 7.3 problems/ information
Another thing is that the fuel injection system is different than most other diesel engines, so your John Deere school won't help much with the powerstroke. The injectors are operated by high pressure oil, rather than an injector pump that pressurizes the fuel, and sometimes you can chase HPO problems all over the place. O-rings sensors and oil leaks can be problems too. If you don't already have a professional grade code reader, you'll have problems finding a lot of the little quirks. Either a high end reader, or an OBD-II dongle with a software scanner is a must.......
