Where is the pcm on a 99 Ford ranger 3.0 - Ford Cars & Trucks

https://www.justanswer.com/ford/m539u-blowing-pcm-fuse-1997-ford-ranger-2wd-3-0-soon.html

2wd or 4wd,
current trans is.4R44E OR 5R44E OR 5R55E.
THOSE 3 TRANNY NAMES ARE JUST BASE LINE NAMES NOT FULL.
why not ask ford this?
lots to go wrong,
A/T boxes are complex. and vast sub-versions exist even 4wd
it has to fit engine end and be same length to tail prop shaft.
must have same gear ratio's
and wire wiring to the connector (TCM/PCM) to the boxes control solenoids. speed sensors and pressure sensors etc.
also even 1 year box will have 2 or more upgrades on box sensors and are not the same. (wrong one used, PCM fails)
The PCM must like this wrong tranny, and most do not. guessing.

the answer is:

• ask ford this, or join a real ford forum that does complex swaps
• ask any tranny REBUILD shop to look it up.
• ask any wrecking yard to look up what other cars match they have this very expensive data base, network to do all that. ask.

If the sticker has faded or fallen off, you will need to go under the dash on the passenger side and remove the kick panel to locate the PCM. The code should be on a sticker on the PCM harness. It is a 4 character code usually 3 letters and 1 number.

sounds like the linkage from the ignition lock cylinder to the ignition switch is broken.

i would start looking for vacuum leaks first,

1-3-4-2 both sides

When the anti-theft light is flashing rapidly then either it is not seeing the key,or the transciever module is not communicating with the PCM. It could be the transciever or it could be the PCM is not powering up for some reason. I would first try replacing the PCM relay in the underhood fuse panel.

It does not have an ignition control module. The PCM (powertrain control module) fires the coil pack based on signal it recieves from the crankshaft position sensor and the camshaft position sensor.

Measure the distance from bolt to bolt, and to the center. If they match then, they match, if not you will have to check the numbers with fords tolerances to avoid an axle wrap. But it should fit, maybe just a little stiffer of a suspension from the 4x4.
