The 1991 Subaru 1.8 liter engine, should have an oil pressure of 40 pounds per square inch. The oil pressure can vary five pounds, either way, and still be safe.
The water pump on a 1991 Subaru Legacy is in the engine compartment. It is found at the base of the engine.

The 1991 Subaru Legacy has a 4 cylinder 2.2L engine
you should be getting at least 48 pnds of pressure that's what the specs are for that engine
Fuel pressure should read no less then 9 LBS. and no more then 13 LBS. And yes it should hold the pressure with key on, engine off.
If you have no spark on the 1991 Subaru Legacy, you should check the spark plugs and spark plug wires for replacement. You should also check the battery and ignition for replacement.
With the engine off then turning it on, it should be between 23 to 31 psi. With the engine running, it should be 13 to 20 psi.
Do they have the same engine? If not, then no, it wont work. If they do, make sure they have the same fuel pressure requirment. If the engine and pressure is the same, they should be interchangeable.
Code 33 means: Vehicle speed sensor (VSS) or circuit
Once the engine reaches normal operating temperture, the oil pressure should be somewhere between 25-40 psi. Even a pressure of from 15-25 is not something to be overly worried about.
On a 1991 Ford Explorer , 4.0 litre , OHV , V6 engine : I believe the oil pressure sending unit is on the drivers side of the engine , below the power steering pump
