Charles, CPS is located low on rear of left side of engine.
Below I posted links with videos to show location, testing and replacement.

How to Test Crankshaft and Camshaft Position Sensors

A little more info would help. Throttle position sensor? How do you know they are reading max voltage? Are you trying to replace the voltage regulator?

Check the crank position sensor. If this goes out, when it gets hot, the sensor will think the crank/timing is in the wrong position. They did this to prevent engine damage in the event that your timing is off. However, when the sensor gets old, as it gets hot, it malfunctions shutting off the engine. Then, when it cools down a bit, all is well.
IF IT IS THE CRANK SENSOR, REPLACE IT IMMEDIATELY. Repeatedly trying to start an engine w/the CPS out can throw the timing off. This happened to a friend's Kia Sepphia once and it locked up her engine.

check the egr and the vacume lines to it,also check the cps(crank position sensor)and the connector

If your stateside the CPS is on the drivers side of the bell housing at approx 11 oclock.They have 1 or 2 bolts securing them.assuming its the 4 litre motor.If its right hand drive the CPS is on the fornt seat passengers side.

well i would think the crankshaft position sensor it bad/in wrong position/or the bell housing holds the crank sensor to far away from flywheel.if my memory is correct anything other than the jeep bellhousing wont work with the jeep fuel ign. system

Crank position sensor has a higher failure rate than it should...however i would not change it "at random" Check for continuity between b&c terminals of the sensor with a digital ohmeter.
There should be no continuity between them (b&c should be marked on connector) No continuity reading is same as when probes are not connected to each other.
I really dislike when people try and help and use terms that owners can't understand ... "check your zxy and qtr then add an abc" dosen't seem helpful. I hope I am as clear as I can be!!!
Good luck.

have you replaces the cps yet.( cran position sensor on bell housing )

Sounds like the crank sensor. One way to check is while cranking watch the tach. If there is no movement then most likely it needs a crank sensor. If the sensor is good you will see a slight bounce in the tach.
