A grounding issue anywhere in the circuit from the air meter switch to the red relay will leave the loop open which allows the pumps to run when the ignition switch is on. This includes the switch itself or the pick up points that open when the plate moves off its resting location. Have you cleaned the plug contacts in the air meter plate plug and receptacle?
