Then check for average voltage from H pin to ground (should be around 2.6V) and from L pin to ground (about 2.3V).


You sure your bm3 mod is not putting too much demand on your stock fuel system where the EKPM and the pumps cannot keep up?
Thanks for the input! No customization has been done, will only apply those once I know all hardware is running smoothly, so, no, bm3 cannot be the culprit at this point.

RE: voltage gauging, I am your fellow weekend warrior without a multi-meter and oscilloscope at hand unfortunately… Any other quick and dirty low tech way to tell between the faulty EKP and LPFP known to the humanity?
