under valve cover harness
hey guys got a guy out here with an 01 f-450. he lives in the building i work in, and he's got a problem with his truck, and thinks it's the under valve cover wiring harness. he's sure it isn't the cps as he is familiar with cps problems. how can we rule out injector problems, or something else? the time the harness went bad on my 2000 f-350 it wasn't very hard to replace, because the guy who did it for me swapped it out in less than a half hour. i watched him do it. this guy out here really doesn't wanna have it towed for something fairly simple. how do we rule out other problems with it? 01 f-450 231k miles.
