Like the title says no power at the fuel pump relay.... all fuses are good, pump will work with the diagnosis box jumped.

I did take the maf sensor out after installing the vpc..... car will run but only if I jump the diagnosis box.

I did find the maf sensor has a switch for the fuel pump... I'm just looking for suggestions at this point.

I did the the pump 12v mod also.

Did you verify that you tapped the correct wires with the VPC and you did not accidentally cut the wires (especially with the age of the cars, that is a more than likely scenario)?
