Thx Stuart,
I had dropped the fuse panel thinking I could check voltages with the
relay in place, but the bundle of wires made it too difficult to do that.
So I just pulled the relay and checked to see that it was seeing 12V.
While the panel was dropped, I looked at the ground 'star' but didn't
check for a voltage drop across it...I should have but it looked clean,
dry and corrosion free. I may have disturbed the ground connections on it
just enough when I tried pulling the wire bundle out far enough to get at
the connectors on it.

Intermittent pump is often a bad ground at the ground star under the dash
behind the fuse panel. I've seen corrosion cause this as well as complete
disintegration of the spade connector.

For all of you who think that the washer fluid pressure is low...
I was adjusting the spray pattern yesterday trying to compensate for the
lackluster spray pressure when the washer just quit on me..no noise from
the
pump but the wipers continued to work. Pulled off the fuse cover and
checked all of the fuses associated with the wipers..everything looked
good.
Pulled out the Bentley schematic and located the relay terminals for the
pump and pulled the relay to check for voltage when the wiper stalk was
pulled..12V + or -...OK
Crawled under the van and dropped the washer tank and disconnected the
wire...hooked up the DVOM to the connector and checked for voltage
there...12V OK...pulled the pump motor off and took it to the bench and
tested it with a 12V battery from my drill...worked perfectly?????
Went to reinstall and while this shouldn't affect the pump, I noticed that
the tubing was crimped...spent a few minutes massaging it back into a
'tubular' shape and finished the reinstall.. pump worked AND more than
enough fluid flow and the fluid takes much less time to initiate.
Still not sure why the pump went dead for a bit.
