I have a 95 F-150 6 cyl 4wd and I had a problem where the oil pressure went
low. I had the oil pump replaced about a year ago so I don't think that is
the issue. Does anyone have any guesses at what it can be? I had the truck
towed home and would like some advice before I take it to be fixed.

Thanks,
pat

Bad sender? Did you check the oil pressure with a mechanical gauge?

No the oil gauge in the truck was all the way down.

Wouldn't it have made more sense to insure that the problem wasn't the oil
gauge or sender before you dove in and disconnected the motor mounts, raised
the engine, removed the oil pan and changed the oil pump, replaced the pan
gasket and reassembled?

I like to start with the simplest solution first and work up from there.

No I didn't do any of that I was just relaying that the oil pump was changed
a year ago so I didn't think that was the problem and was looking for other
causes.

Ahhh, cool. Any shade tree mechanic can remove your oil sender and test the
pressure with a pressure gauge at the block.

The oil pressure gauge in a Ford truck is nothing more
than an idiot light. It's set to read about mid-scale when
the oil pressure is enough to keep the warning light off.

You need to verify that you really have no oil pressure
by using a mechanical pressure gauge, not the one on your
dashboard.
