Fuel filter - don't know when it was replaced.

Don't know about OVP - when it goes does it not cut fuel pump power?
I can hear the FP running and can measure voltage at the connector under the rear pass. side seat. I am also not getting the ABS light.

Is the FP supposed to prime every time you turn the key to ON? Mine will do it once, then not again for several seconds regardless of how often you turn the key or remove the key and they re-insert and turn.

Is there a delay or pressure monitoring at work??

Also, No fuel at regulator vacuum line.
