Two months ago my car broke down, engine stalled at could not start. Eventually, after changing the in-tank fuel pump, the problem was resolved by replacing the fuel pressure sensor. Now the same problem recurred, but this time it seems to be the PEM, since all other related parts have been replaced.

The authorized Volvo workshop has discontinued permanently. Does anyone know where the PEM located? I head it was located somewhere around the fuel tank, but could not find it.

Thank you
