My 1986 201 stalls at idle. It will fire up fine. If you keep a little pressure on the throttle, it will drive fine. In fact, it will drive fine at speed on the highway. However, as soon as you lift from the throttle -- at stop lights or at any stop -- it immediately cuts out.

Replaced OPC. Crankshaft Position Sensor appears in good shape. Fuel pump appears in sound order.

Does this sound like a faulty Fuel Pump Relay?

Thanks for any and all assistance.
