These are the error codes:

None of the above. Stop looking for the most expensive comportment to replace first. This is a correlation issue.
P1690 Fuel injection pump ckp sensor dows no agree with ECM ckp sensor.
P1693 DTC detected in companion module

No symptoms posted. just how to turn a bolt. ok.
id not attempt to force it out, unless new one in pocket
right? if you break it you are DIP, dead in pavement.

if the scan tool says its good, why do that. really?
P0336? or P0340/1? why not just say the DTC does,
the ECU reports even 1 drop in 10, so did it?
most are good, but getting parts off rusty engines can be very very hard.
which engine is there, why post with out first declaring engine.
3 engines they had. 4.0L , 4.7L and diesel..

try pen oil? penetrating oil, yet? soak wait, soak wait,pray, repeat.?
WJ jeep
CKP (old SAE name CPS)
using correct name allows searching in the FSM book more easy.
the crANK SENSOR. p1690"S Use real scan tool?
p0320'S

the 4L is on bell housing top. seen below.
the 4.7 liter is above. the starter.

this?
or the 4.7L? (its totally different)




part #1 is CKP and take out bolt, and the wiggle it out.
if diesel , say so.

Try going to your local Autozone store and ask them to check
your vehicle for emissions and other engine problems.
This is a free service. They will show you a print out of the probable causes of the problem you are having and the cost of the parts you need to fix your vehicle.

Good site, there. And you could type in each code one at a time in the "search for anything" box above, and pick and choose among what's good and relevant for you. It's all good, bro, lol. I see you have a repeating 322.

You will need the dealer to scan the system ans see what is faulty, Sorry you need a special scanner and the repair manuals to get a handle on this. I call them as i see them, sometimes the dealer is needed.

The p1690 is the transfer pump code I believe. Unfortunately the engine will run without a good transfer pump for awhile. Eventually the main injection pump will fail due to lack of fuel pressure. The main injection pump requires 6 psi minimum. When the main pump fails and this is the unfortunate part it's trash. It is possible you just lost enough fuel psi that it died and a 160 dollar lift pump will fix you up. I would suggest a fuel psi gauge on all 98 and a half through 2002 dodge diesels. A 80 dollar gauge can save you about 1800 dollars and that 1800 is if you do it yourself.

P1690-FUEL INJECTION PUMP CKP SENSOR DOES NOT AGREE WITH ECM CKP SENSOR

anytime you are installing aftermarket stereo in car you should purchase wiring harness converter which comes with schematic, but if you insist on doing it old school youll need a repair manual to show color codes on wiring or a 12 light meter but lucky for you I looked up the wiring codes online heres link:
