I keep getting error code P0193. Must be accompanied with my heavy foot as it never shows when the wife drives the car. Car is a new to me 2008 XK with about 30K miles. PO replaced the fuel pressure regulator twice (first replacement claimed to be defective) a little over a year ago, so must have been a persistent problem. I am thinking an 11 YO car with only 30K miles must have been sitting at some point creating a shellac problem? Thoughts?
Check/change the fuel filter.
Looking at the code that is for high pressure? If it is then I don’t think the fuel filter is going to cause that, it would be more likely to cause a low pressure reading I would think?
Have a read of this thread, it may help.
