Fuel SOLENOID Power comes through coolant temp switch? 3208T

[xz3kg7]

I need to get my terminology right. I said sender in an earlier post
instead of solenoid.

I've had a couple of random electrical problems and I'm trying to
figure something out.

The hot wire for my 87FC35 (3208T) fuel solenoid goes through what
looks like a coolant temperature sender/switch on my block. If I'm
under the dog house, the coolant "sender/switch" looking thing is
about 6" northeast of the fuel solenoid itself. (It is screwed into
the engine and when I loosen it antifreeze comes out.)

I'm suspecting that this sender/switch is bad.

Does it make sense that this would be wired this way? I presume if
the engine overheats it opens a contact and quits sending power to the
fuel solenoid, therefore shutting down the engine before it can be
damaged?? Anybody know?

Thanks,
