no oil pressure

After getting the engine out and with the side covers off, I can see that the oil pump is turning and the chain that drives it is intact, what else could cause the pressure to drop to nothing, could it be an internal oil ling broken? RCM

Did you check the pressure by putting a gauge at the oil switch? ... Yes, you did ...

It's possible the pump itself is just worn out. The gear fit is very precise and too much clearance is what makes them fail to pump.

There's been some trouble with oil changes and needing to burp the filter to turn the oil light off, but I don't know if that can also stop pressure from building in the engine. (wouldn't think so) Have you cranked it any with the oil sender fitting open, nothing threaded into it? It would suck to find out it needed burped, but at least you wouldn't have to split the case.

It was ok and the next time I started it the light was on and I put a gauge in it , no pressure, I wouldn`t think the pump would go quickly because of wear, I`ll find out when I split the cases.
