Hello, Gentlemen
I hope you guys can help me I changed my fuel filters on my 04 6.0 and it will not start when it is cold it sounds like I have an air leak by the secondary fuel cartridge but it is not the cap tried new one from buddy,it is shooting off two codes first being 0223 TPS switch B circuit range performance problem 2nd being 0232 Fuel pump Secondary high please help!!!!!!!

 

Did you unplug anything down low when you changed the fuel filters, or maybe knock a wiring harness off the fuel pump?

 

No I checked and checked ,but I keep hearing air at the secondary when I turn the key???

 

Does anybody have any ideas
