Fpr solenoid and bp solenoid

i was checking my bp solenoid after startup, which appears to be receiving power but not actuating. and i noticed that the bp solenoid and the fpr solenoid were power cycling in exact sync with each other. i was expecting the bp solenoid to cycle due to the computer detecting a problem, but not the fpr solenoid, and definitely not in sync to each other. Is this normal behavior? Or do i have a couple lines crossed? I’ve been troubleshooting my bp and I don’t know anything about the fpr setup.
