SOURCE: 2002 ford f150 4x4 manual transfer case vacum

The vacuum shift solenoids have power to one side of them at all times.
The GEM applies ground to them, to activate them, after the shift on the fly position confirm from the trans case.
The power to both should be on the White w/ Light Blue stripe wire.
Ground to them ( from the GEM ) is
2WD : Gray w/ Black stripe wire
4WD : Red.

The only TSB I know of is for the 04-06 MY trucks, for the IWE solenoids ( the kind without the water shield ).

Did you jack up the front end ( and support correctly ) turn the key to the run position ( do not start ), and shift into 4WD, and check the front drive shaft ?
If the shaft still turns, the problem is in the transfer case, if not you are looking in the correct place.
The GEM will not signal a vacuum solenoid until the transfer case has shifted into 4L or 4H ( 4 switches that are the return signal to the GEM ). Could be a problem with the connector on the transfer case ( think it is a 8 or 10 pin connector ) to the contact plate position switches in the trans case.

There is a manual front ale cable, but I would think you would want to confirm why the GEM is not signalling the shift solenoids, prior to replacing them

VACUUM DIAGRAMS (See Figures 1 through 85)

Below is a listing of vacuum diagrams for most of the engine and emissions package combinations covered by this manual. Because vacuum circuits will vary based on various engine and vehicle options, always refer first to the vehicle emission control information label, if present. Should the label be missing, or should vehicle be equipped with a different engine from the car's original equipment, refer to the diagrams below for the same or similar configuration.

IF this is a case that the IWEs will not disengage, it could be the IWE solenoid or the vacuum lines to the IWEs. Could also be a problem with the vent lines from the IWE ( the other vacuum line that runs up into the engine compartment, and just hangs there ).

This is the block diagram of the vacuum lines for the IWE ( not actual routing ). You can use a vacuum pump / gauge to see if the lines will hold vacuum. Don't be surprised if the vacuum lines test OK, there is a TSB on the IWE solenoid where it could ingest water, and allow water in the lines, which will not keep the IWE gears disengaged.

Check all of your vacume lines. If it isn't a vacume line it is most likely the O2 sensor.

Truck wll hesitate and then die


Id say he accidently disconnected a vacume line ou there is a loose connection. Another possibility is that a plug or wire got damaged durring the removel, when removing ploug wires it is important to grab only by the boot I suggest starting with \
check vacume lines then remove wires one at a time and inspect to see if contacr is visible in boot and not damaged. Next would be to inspect plug gap and for cracked ceramic on all parts ot plug.
