Low coolant sensor

Does a 1988 Toyota pickup with a 3.0 v6 have a low coolant sensor that will prevent it from starting if the coolant is too low?

No. there are coolant temp sensors but that shouldn't stop the engine from starting.

There is a clutch sensor that prevents the starter from cranking without the clutch being pressed. I suppose that could go bad.
