Default 2004 ranger 4.0 sohc. cranks/ no start

As the title implies. Wife drove it home from work, no issues. Went to run an errand about an hour or so later, it started and briefly ran (rough), then died and wouldn't restart. Would like to do electrical checks first. Searched but couldn't find a schematic for powertrain
control for an '04. Anyone know where I might find one? The fuel pump was changed a year or two ago, can't remember, but that doesn't mean
it's ok necessarily. I am getting constant power thru fuse #23 in the underhood power distribution box, key turned ON or Off, makes no difference, 23 is always lit. This seems wrong to me, but I am totally open to any ideas or corrections you guys might have pertinate to what
I have tried so far. Thanks in advance....jim

Turn the key forward and check the schrader valve on the fuel rail to see if it has fuel pressure. If not, then check the fuel pump inertia switch in the cab under the dash. See if it got tripped somehow.. It does happen..

If all of the fuel system checks out, then check for spark at one of your spark plug wires.

Once tripped those switches are junk.... A mild fart will trip them once used.

Good deal! Glad to have confirmation that my suggestion ended up being the problem for once. We don't often hear back from the original poster on these threads..

Luckily the switches are an easy find/fix and easy to swap out as well.

Now, tell the wife to slow down and stop ram-jamming over those potholes so fast! lol j/k
