Hi, I am new to the site and I just installed a Procharger with a two core intercooler into my 2004 Silverado 2500HD 6.0, 4L80E and 4.10 gears.
I couldnt use an FMU because no return on the 04 so i used 42# delphi black injectors and an MSD voltage booster. When installing the voltage booster I knew i need a grey and black wire for the fuel pump. I reached up top but instead I got the evap solenoid plug. I ran 12volts to this solenoid and then got the code P0452!!! I removed and reconnected the wires and got the fuel pump.
I still get the code and the truck is a little weak on the bottom but rips upstairs...
Do you think i ruined the solenoid? Is it hard to change?
I also have a custom burn on the PCM.
Any help is appreciated. I did fab quite a bit because they don't make a kit for the HD....
I cleared the code twice but it comes right back.
Thank you
Dan
