Replaced the Timming belt.2001 Dual cam focus Z Tech 2.0 L Set to TDC as per manual. Compression test good. Started car RPM keep going up run around 2200. Retarded the Timing back center of dead center . Problem remains
Need advice. Thanks Vili
I did install the timing belt working it counter clockwise with 5MM tool intalled at end of cam shaft. I also loosened the cam shaft gears to set the belt tension to correct position once set I tightened the tension pulley

Replaced worn timing belt. Used a 5mm flat stell to hold the cam shaft in place. Unable locate any marks on drive shaft pulley. Used a Srew driver upside down to locate TDC. I set fist on the very top. Did compression test good. Started engine running too high 200RPM does not change if I step on the gas it keeps going up. Shut engine down. Reset the timming belt as per manual retarted back one nuch no change to RPM. Still too high. Trodle cable is ok

Your valve tiiming is way off. you didnt work counterclockwise installing the belt keeping it under tension. and pay close attention to cam positions the half moons face up pic here
now for the correct position of crank pulley
here is the full way to do it just make sure you start at crankshaft working counterclockwise keeping tension on belt as much as possible and when finished always turn engine 2 revolutions with a wrench on crankshaft bolt and double check the alignment before putting back together. but here is the link http://www.autozone.com/shopping/repairGuide.htm?pageId=0900c152801ecf2a
you stated this (Retarded the Timing back center of dead center . Problem remains) please elaborate are you talking about ignition timing or did you change something with the timing belt?you stated this (Retarded the Timing back center of dead center .

after you have the crankshaft pulley off; there might not be marks on it so when you install the belt completely and tighten tensionor pulley you must put back the actual cranshaft pulley just temporary to see the marks on pulley and if they line up. desertfox52 said he saw no marks on crankshaft that is why i am posting this. you must put back on the actual pulley just temporary and make a few revolutions by hand and then double check to make sure everything is lined up. now remove the pulley and start putting back the plastic sheilds and put back together the rest. after you have the crankshaft pulley off; there might not be marks on it so when you install the belt completely and tighten tensionor pulley you must put back the actual cranshaft pulley just temporary to see the marks on pulley and if they line up. desertfox52 said he saw no marks on crankshaft that is why i am posting this. you must put back on the actual pulley just temporary and make a few revolutions by hand and then double check to make sure everything is lined up. now remove the pulley and start putting back the plastic sheilds and put back together the rest.

Tip: The max point reward for answering a question is 15.
i am guessin you have the 1.6l engine. from what i recall a few months back while reading through a service manual, the ideal compression ratio should be about 190psi, with a minimum ratio of 170psi. the difference in the cylinders should not exceed 20psi. based on the results you have given, i think you have a serious problem. i would recommend you try a "wet' compression test. that would atleast give an indication of whether or not the piston rings are worn out as well.
to answer your second question, the 1.6l has a total of 16 valves, four per cylinder, 2 exhaust and 2 intake.
The IGNITION timing on your Ranger is computer-controlled and is not adjustable.
Should the camshaft drive belt/timing belt jump timing by a tooth or
two, the engine could still run; but very poorly. To visually check for
correct timing of the crankshaft, auxiliary shaft, and the camshaft
follow this procedure: There is an access plug provided in the cam drive belt cover so that
the camshaft timing cam be checked without moving the drive belt cover.
Remove the access plug.
Turn the crankshaft until the timing marks on the crankshaft indicate TDC.
Make sure that the timing mark on the camshaft drive sprocket is aligned with the pointer on the inner belt cover.
Never turn the crankshaft of any of the overhead cam engines in the
opposite direction of normal rotation. Backward rotation of the
crankshaft may cause the timing belt to slip and alter the timing.
REMOVAL & INSTALLATION
See Figures 1, 2 and 3
Fig. Fig. 1: Timing belt cover on the 2.3L and 2.5L engine
Fig. Fig. 2: Timing belt assembly on the 2.3L and 2.5L engine
Fig. Fig. 3: Releasing the timing belt tensioner using a special tool
Rotate the engine so that No. 1 cylinder is at TDC on the
compression stroke. Check that the timing marks are aligned on the
camshaft and crankshaft pulleys. An access plug is provided in the cam
belt cover so that the camshaft timing can be checked without removal of
the cover or any other parts. Set the crankshaft to TDC by aligning the
timing mark on the crank pulley with the TDC mark on the belt cover.
Look through the access hole in the belt cover to make sure that the
timing mark on the cam drive sprocket is lined up with the pointer on
the inner belt cover.
Always turn the engine in the normal direction of rotation. Backward
rotation may cause the timing belt to jump time, due to the arrangement
of the belt tensioner.
Drain cooling system. Remove the upper radiator hose as necessary. Remove the fan blade and water pump pulley bolts.
you will need to open the engine up if you can not turn the cam fully. something has been bent or broken or else it will turn. by breaking your timing belt was it shredded? if so you do have internal damage
Put the engine at TDC compression stroke , Thats when the valves are
both closed on No 1 cyl and the piston is on its compression stroke
.then align all cam and crank marks. set distributor/rotor button on No 1 cylinder (rotor
pointing at #1 plug wire) . rotate engine 2 revolutions and recheck all
marks. Fire away
Remove the timing belt cover. Set the crankshaft/piston in the correct position. Now check to see if the camshaft sprocket is align with the witness mark. Both the crankshaft and camshaft has to be aligned else your timing is off and you will have to take the belt off and re-installed correctly. Even if off 1 notch.
Hopefully you will never buy another car with a timing belt. It's a false economy saving.
You have to leave all of the slack at the tensioner. Get the timing marks lined up on both of the cams and the crank. With the slack left at the tensioner, release the tensioner. It is okay if the marks move a little after this. Manually turn the engine crankshaft twice and then MAKE SURE THE MARKS LINE UP! If they do after two revolutions of the engine, you are good to go. This applies wether or not you are at DTC or not! Remember that!
Please remember to rate this solution.
if your plugs are on top, take the 1 cylinder plug out an insert a screwdriver inside of it. turn the cam until the screwdriver is to the last point of coming up. do this slowly because you don't want to be on the down stroke of tdc
now for the correct position of crank pulley

does the RPM go up and down or does it stay steady at 2200?
