Changed oil. Oil level not low, not over full.

Oil Pressure light stays on and no start.

What am I missing?

No cranking. No sound(s) whatsoever.

First check that the PTO switch isn't pulled out and that the parking brake is set. These are the main switches in the safety interlock that would not allow it to crank. After that you'll have to start tracking down wiring. I assume it ran before the oil change.

PTO and park brake off.

Ran. Changed oil. Oil Pressure light on with no start, no sounds.

Weird it should or could be wiring. But, that's the nature of engines some days.

You said parking brake off it needs to be on.
PTO off
Parking Brake on
Clutch pedal depressed

Here are a couple of pages from the service manual that cover the starter inhibit circuit.

To clarify, foot brake on, park brake not engaged.

Thank you for the pages.
