Fuel Pump Relay cuts out when steering wheel turned to left! 700 1988

I have been chasing a fuel delivery problem in my 740T for a few months. Car would die from time to time but always restart after sitting for 10 min or so. The other day it would not start at all. Tapping on the fuel pump relay with the starter engaged allowed the car to start and suspecting a faulty relay I limped over to IPD and got a new one. This was not the cure. I decided to drive with my finger on the relay to see what I could learn and to my amazement the relay switches in and out as the steering wheel is turned to the left. Not only some of the time but as if they were wired together! On neutral or trailing throttle it feels like hesitation, on the gas it is very abrupt. Anyone have experience with this? What in the steering column or adjcent to it in the footwell is tied in to the ECU or fuel pump relay that could be causing this?
Perhaps a grounding point?
