1995 Rangers had no PATS security, '99 with V6 engines and 01/02 for 4cyl Rangers
You can use another PCM used or new, from/for a 1995 Ranger 3.0l with automatic
2WD or 4WD shouldn't matter, but manual or automatic does, and of course engine size.
1995 was the first year Rangers got the newer model computer(PCM), the EEC-V, Ford goofed up a bit with the OBD2 protocol on this first model so many OBD2 scanners can't "talk" with it or get oddball responses.
So mechanics that don't know about this can often misdiagnose PCM issue when there is none.
With a no start but cranks fine you need to do a 50/50 test
remove air tube from intake manifold
Open throttle and Spray some Starter Fluid or gasoline in to the intake
Then crank the engine
If it starts and dies then fuel is the problem
If it doesn't start then spark is the problem
No fuel is usually failed fuse, fuel pump relay, inertia switch or fuel pump in the gas tank
No spark is often bad Crank Position(CKP) sensor, and on 3.0ls failed Cam Position sensor(CPS) can cause no start.
As Jeff said PCM is way way down on the list of possible problems, they can fail, just very very unlikely to fail
