Hi i recently bought a 2007 octy vrs the previous owner had butchered the hp fuel regulator connection (pic added ) he'd soldered the wires to remaining pins what left..

So after time they became free and then came the epc light and code p2294..

So ive replaced pump and added a new connection plug but i still have the epc light on and same p2294 code..

Any ideas on what i could be missing ive basically replaced all the broken parts but have the same existing problem..

Are there independent fuses or relays for the hp fuel regulator..

Help.......
