Resolder the OD relay. $0, 15 minutes, no risk, clean 'n easy work.

If it does nothing, you're out nothing.

Resolder your fuel pump relay and the "radio suppression" relay, too.

The fuel pump and suppression relays gave trouble in wife's '91 740. I got frustrated and resoldered every relay in the car.

Note -- you might have a chaffed wire from push button to relay, inadvertently causing it to shift in and out. But try resoldering the relay before you chase wires.
