JUST REPLACED MY PICKUP FOOT IN MY FUEL TANK. CLEANED THE SCREENS & MY MIXING CHAMBER. THOROUGHLY CLEANED & INSPECTED FOR ANY CONTAMINATION. INSTALLED SENDING UNIT. PRIMED SYSTEM & ENGINE RAN GREAT. DROVE IT FOR MAYBE 5 MILES. GOT BACK HOME, R&R AIR FILTER. TRUCK SAT OVER NIGHT. STARTED ENGINE & IT RUNS LIKE CRAP! WHITE SMOKES PRETTY BAD. GIVE IT FUEL & IT BOGG'S DOWN. WTF!!!!!!!!!!!!!!!!
I HAVE NO IDEA HOW TO TROUBLESHOOT ANYTHING. I HAVE NEVER SEEN, MUCH LESS DIAGNOSE A 7.3L WHERE WOULD BE A GOOD PLACE TO START.
OPENED PETCOCK FOR MY FS FILTER & IT DOES HAVE FUEL. OTHER THAN THAT, DUHHHHHH

Sounds like your not getting enough fuel..
Does it start fine? Does it idle fine or idle pretty crappy? Soon as you burp it does it just stumble and come back or does it stay running chitty? How is battery voltage and alternator power?

:pointlaugh: had my head up my ass on this one. when I replace my air filter last night. I put rags in the intake pipe so when I blew out my air box, dirt wouldn't contaminate anything. welp, I left the rags in & forgot to take them out. when I opened the hood to look for anything. a light bulb went off in my head. truck runs great turbo is fine. im a retard. 01 f250 7.3 saw black smoke for the first time out of this thing. that was the second time I've done that. first time was on a 3406 CAT. luckily nothing got damaged that time either.
