Thanks for the reply Jim.

The fist time it stopped running I did check all the fuses under the hood and gave the relays a thump. So it just may be the problem. I'll lay hand on it tomorrow and check the relay connections are clean. I don't remember hearing the pump running. But I normally don't hear it if the cars been running for awhile. Only after it sits overnight or for a long time do I hear the pump.

Thanks again. Bob
