Hi all..ok so here is my story..my dad has a 2003 7.3L it has 191000 miles on it. He told me that its been hard to start and that he has to let the fuel pump cycle with the key several times to get it to start and once it does it shoots out white smoke. Now i am a diesel mechanic for a local freightliner shop but i have not done much work on powerstrokes. I do know that it is nearly the same as the CAT huei system. I also believe that its hard to start cuz its losing its prime thru injector leakage..which would cuase the white smoke..now do these injectors have anything similar to the CAT trim files that need changed by a computer or is this something i can do for him in my garage? Also are the glow plugs inside or outside of the valve cover? Also what are some average prices for injectors and glow plugs? Any advice is appreciated. Thanks in advance.
