René, if you have doubts about the fuel pump control module you can bypass it as below - module connector pin1 to pin 5 and pin 4 to pin 8. (Note wiring colour codes change between module and pump, black becomes positive and white return). It may throw a fault code but engine should run.



I understand they are normally reliable but bought one as a spare here recently.

I cannot comment on measurable voltages but imagine a PCM output from module is controlled via an FPC signal (white wire) from ECU pin 81.
