Out of ideas
My 2002 Ford ranger 4.0L has a crank no start. I got 50 psi at fuel rail. I got spark from plugs. Changed crank sensor. Cam sensor is good. It will start when I spray starter fluid. But will not start on its own. Does anyone know any idea what's goin on or what's the next step I should take. Thanks

That vehicle has PATS.
Are you using a correct (chipped for your vehicle) key?
Make sure the "anti-theft light" illuminates when you turn the system ON.
You may have a light, but the bulb may be blown.
Even with gasoline sprayed into the cylinders, you need compression to fire an engine.
Check each cylinder's compression.
Remove all sparky-poos and shove a compression tester into each cylinder and crank the engine.
Get a helper if your particular gauge won't stay in the spark plug hole.
Top compression is 150-160 psi. Each cylinder might need 4-6 pulses to reach maximum.
Pulse each cylinder the same number of times. Wright down your findings.
Cylinder layout below.
