After run coolant pump??? 86' 5KCSTQ

["Martin Pot" <paulnet@ipa.net>]

After run coolant pump works smoothly if I put 12 V on it. Fan comes on when
I bridge the thermoswitch. When I disconnect ground to fan and bridge
thermoswitch, I hear the relay but coolant pump does not work.There are 3
wires at the pump, 2 of them are together. If I separate the two mating
wires and do the bridge test, the relay won't click. I just can't figure it
out. Thanks, Martin.
