99 f250 7.3 losses power when i try to pass or just get on it wot,no smoke seen,no codes showing, ideal good and revs up good out of gear, but when trying to pass it just bogs down and very little passing, fuel filter and air filter changed a couple months ago, i have had very little problems with engine, gem replaced 2 yrs ago,trans 4 yrs ago, not sure if i'm looking at a fuel problem or sensor problem, any guidence would be appreciated, thanks

 

How many miles on truck ? Have you done the in tank mods ?

 

258,000, I haven't started yet, trying to see what is the best to start with.

 

checked codes last night after this happened, no codes showing, started checking sight to see if any else had this problem.

 

Lack of fuel pressure, HPO, or boost come to mind but we need a lot more info.

What scanner are you using? Most will not read the 7.3 codes. We will need boost, fuel and HPO numbers to even start. Anything else will just be guessing.

 

Sounds like you might have plugged screen in the tank. Try to blow some air back threw the fuel line, pull the line at the pump and blow air back into tank.

 

I'll go and try that, I have the actron obd ll auto scanner and thanks for the info

 

blew through the screen in the tank, still no go, 1500 to 2500 rpm and no get up and go, guess I'll go get a fuel pressure gauge set and check pressure and check injectors
