OBD I ( not OBD II) codes question

on the 95 GLX's, with OBD I, will any code cause the check engine
light to come on? Or only emissions related codes? I think OBD II is
different, and lights up with any codes stored. Right?

I suspect my secondary coolant pump is not working, I believe it
should code on the OBD I, but don't have a light indicating any
faults.

In otherwords if the check engine light is off, does that mean there
are no codes to be pulled on an OBD I car?

Thanks!

Will the pump set a fault code, NO!

OK then how do I verify if the pump is operating ? Remember, this is
the VR6 with the electric aux coolant pump. I suspect it is seized.
(I really thought I saw something about it setting a code based on
amperage draw in Bentley, but can't find where I thought I saw it.)

Put a test light or volt meter across the pump connector! If you got voltage
and you can't here the pump run then it's bad. It's that easy.

Doh, I guess so. I was trying to hear it with the engine running (

Thanks!

from memory it should only run after the engine is off to lower coolant
temps. There would be no need to use it when engine is running, that's the
job of the regular water pump.

Well that would make sense, unless the back of the head has water flow
problems. I understood the pump to run at all times, not just shut
down.

What I do know is that even on cool days, the rad fan now runs after
shut-off, so I can't hear if the pump is running, and there is
gurgling from the block....no coolant loss though. The gurgle
(especially) is why I suspect a seized pump. The fan? It may be an
additional symptom, or something else.
