My guess would be no, it has a large, locked connector and it is not
where it could be broken off. If it were not making a connection it
should be reading nothing.

I would have it fixed very soon, sometime before the engine goes. I
didn't dig through my manuals but oil pumps have a relief valve and if
it fails you can get very high/low pressure depending on how/what part
of it failed. Getting a reading without the engine running may still
be the relief valve or the sending unit.

What type/weight oil are you using and how often do you change it?
