380 SE stalling
My '81 380 SE has started stalling at infrequent times. There is no warning, the engine just stops. Usually at stop lights, but sometimes just going down the road. I suspect it is the fuel pump relay. Is there a way to test the circuits to determine if the problem is with the relay or some other problem with current not getting to the relay? I have checked the wiring at the fuel pump and the ignition switch and I can't make the system malfunction in the driveway. Any ideas??
