Ok here goes, not long since i have had my car remapped, fuel pump, and fuel reg, always use shell super, driving home lost boost, half a bar, peaks usual 1:5 bar, it was as if no fuel or spark, used the pis3 to scan for faults, none, restarted the car, was ok, back to normal until tonight, same thing, this time i put my scangauge on and scanned, got a fault code P0230 - fuel pump controller, is this the fuel pump or is there another part I need to be looking at.......
