Hi People, first time posting so be gentle with me! I own a P38 2001 (X Reg) 4.6l V8 Vogue and recently took it for the engine to be de-carbonised. I was told that when they by-passed the fuel pump via the terraclean machine the engine would not start! Do we know if there is a way to trick the ecu into thinking the fuel pump is still attached? Any ideas would be appreciated! Cheers Els.
