My name is ***** ***** I am a professional here at Just Answer. I noticed that your question had not received a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

The code you have here is for the transfer/lift pump circuit.Since there is an after market lift pump if it is the incorrect lift pump this can cause this code to set as well as cause high fuel pressure issues to the injection system/pump and may be causing fuel in the engine oil.I have seen allot of issues with after market lift pumps and had to replace it with the correct style pump before.This sounds like what needs done here and then the fault codes cleared out/erased to see if the code comes back.

If more help is needed, use the reply tab to continue our conversation.

Thanks Pete
