Which engine do you have?
Please elaborate on 'it won't start'. Does it turn over? Does it just click? Etc...
The more details, the more chance someone can help you.

Unfortunately, changing the PCM is not a plug and play event. (Inless your Ranger is a 4 cylinder)

Passive Anti Theft (PATS) is built into the PCM. Uses a sensor at the ignition switch to check a chip in the key.

A replacement PCM won't recognise the vehicles keys so you've likely installed a fresh "no-start" cause.

Where did the replacement PCM come from? Any chance the supplier might have one or more keys that PCM would recognise?

Else, look to the Forscan app with a bluetooth OBD2 reader to program your current keys into the new PCM.
