Hi, Iam new to the site and have just installed a procharger into my 2004 silverado 2500HD with the 6.0, 4L80E with 4.10's. I was unable to use an FMU because there is no return line so i installed 42# delphi injectors and an MSD voltage booster. when installing the booster i reached on top of the gas tank but got the wrong plug. I put 12volts to the evap solenoid rather than the fuel pump and i got the P0452 code. I reconnected the solenoid and hooked up the fuel pump. I cleared the code twice but it keeps coming back.
Did I ruin the evap solenoid?
Any help would be great, procharger doesn't make a bolt in kit for the HD but I am almost done..
I also have a custom burn on the PCM.
Thank you in advance for any and all assistance.
Dan

 

I would say yes. These solenoids have been going faulty after a short time anyways so there is another set up to get so it more durable.

 

Do you have any info on the "other setup?" My evap solenoid $hit the bed too.

 

It should be covered under warranty at the dealer. If not ill try to find the part #'s for ya.
