if hydraulic operation then replace the master cylinder as the compensating port is blocked . If cable clutch then check adjustment and connection to the throw out arm

If you removed the pin and it still won't budge. Bite the bullet and replace it all. I replace all of it anyway. I don't like taking chances. Since your doing it yourself, your saving a load of shop rate money..Do it right.

RELACE THE PRESSURE REGULATOR ON THE FUEL RAIL

If your transmission is slipping, it typically means your clutch packs have become worn out and no longer have any friction material on them. If this is the case, no amount of adjusting will help. It is time for a rebuild of your transmission.

ARE THE HUBS LOCKED IN FIRST? FOR YOU HAVE TO LOCK AND UNLOCK THOSE HUBS FROM THE OUTSIDE.. EACH TIME YOU GO INTO 4X4 AND WHEN YOU GO OUT OF 4X4 TO 2 WHEEL..DRIVE. OR YOU DON'T HAVE A FRONT DRIVE SHAFT GOING TO THE FRONT AXLE?? OR ITS BROKEN OR THE TRANSFER CASE IS BAD??

If it's cable actuated clutch, the cable may have snapped, which is also indicated by the clutch pedal dropping to the floor or becomes lighter to press. Check at the transmission bell housing, the clutch lever may have been broken or bent. If it uses hydraulic system, the slave pump may have been dislocated, at the transmission side.

You are doing it wrong probably.
If you want to test current to the glowplug, remove the wire and test between it and ground.
If you want to test the glowplug itself, then use an ohmmeter. That is because you don't know what the resistance should be in comparison with the test light, and it sounded like you were testing it in parallel. If the glowplug drew a lot of current, which it probably does, then it would **** so much current way from the testlight, that it would not light up. In general, bad glowplug either go to 0 or infinite resistance, but an ohmmeter will still be more accurate. A test light can be used, but you need to put it in series, not parallel as you would with a light bulb.

I would check out the heat and ac switches. They are notorious on older fords. May be available in aftermarket stores that sell the HELP products.

Not normally as there is no adjustment on the clutch slave cylinder push rod . I would check that the clutch release arm is allowed to return to the rest position and that by pushing it further off you can get free play at the arm. If that is the case replace the clutch master cylinder as there is a blocked compensating port that is not allowing the fluid return to the reservoir. Always do the cheapest fix first.. If the rod is almost at the bottom of the cylinder then I would say that you are in for a clutch kit replacement job.

Your truck is a 1997. Ford didn't offer a V-6 in 95&96. The more specific and detailed the information is, the better and faster I can try to help you. Excessive Fuel consumption can be caused by several different failures. A clogged air filter, dirty or defective fuel injector, damaged or faulty EGR valve, loose distributor, change in the timing, increased back pressure, tune-up is needed, or O2 sensors are clogged or defective. These are all possibilities, please list what you have checked, what you have found, and what the codes are (just post the P___, code/s. No need to post what the code means). If you don't have your own code reader. Autozone will read it for free. You will need to keep the car running if shutting the car off will shut off the engine light. Note: Bring someone with you so the car isn't left unattended.
