A good start, (no pun) spark renewed parts
good. always good. a full tune up.. for real. (spark)
that distrib device is called a CMP, cam sensor!
the flywheel has CKP sensors. to...
but the reason you cant find this is you lacking a scan tool.
the PCM can cuts spark for many reasons.
the ASD relays does that. by command of the PCM
The PCM drops the relay for 1 to 8 reasons.
minus 1 , your car has no IMMO SKIM key.
but here is how to diagnose all JEEPS, (not fake MK jeeps)
first is to understand the ASD relay.
http://jeepdied.com/ASD.html
to do the tests takes 2 persons, unless you are a Xmen. guy.
the JEEP LAW OF 2 SECONDS must not be ignored,
2 full seconds. rule.
this rule applies to spark and fuel,
1:fuses good. test them.
(key on CEL glows, check engine lamp must glow or PCM has no power) does yours?
2: man 1, cranks. (car can crank with DEAD PCM) yup.
3: man 2 , (or WOman) tests spark using a test spark plug
at say #1 front, (easy bend over) lazy we are.
use a real spark plug. ok>? new. or not shorted.,
you ground the shell (this is a 100 year old test, not magic and is done by every mech, alive.) google how to test spark
and not get electrocuted, (got a pace maker?, keep hands in pockets)
4: the key on ASD closes and engine cranks and spark happens for 2 seconds, or not, if the spark ends just as the ASD drops
you KNOW NOW FOR A FACT THE PCM DID THAT ON PURPOSE>
a hard cold fact.
if there was not spark for 2 full seconds, then sparks dead.
the PCM must be scanned.,
if you cant scan you get to shot gun all day.
i have a scope , you dont but i can see if the pcm is pulsing the COIL.
you cant. so get to guess that too.
if the PCM is not pulsing said coil (lets pretend coil is good, i can bench test them, easy)
then the PCM has BAD INPUTS>
CMP
or CKP
tops the list. of shot guns, seems like 1000s replaced here
and not one fixes it.... but goes on.. .. and on because....
best is to own a scan tool to fix any jeep 1991 to now.
or go broke every time a part gives up the ghosts.
the keyon 3 times tests.
can find problems , but NEVER ALL problems, its blind to many.
its just toy really, but has value, if if works.

If the crank sensor (reaR at bellhousing) is dirty, will not start, clean up and visually inspect
SOURCE: 1992 jeep wrangler with faulty acceleration. It
It is possibly the O2 sensor. I had some issues with early 90's 4.0 liters where the O2 sensor would stick rich under heavy acceleration and would cause it to lean out and bog down. It felt like a rochester four barrel flat spot on an old chevy. I hope this helps.

then i would replace whats called the hall effect sensor its that black plastic plate you see when you take dist cap off. just pull rotor and lift up the sensor.dist cap is what holds it on.also under the sensor will be a stamped sheet metal piece that looks like the top of a castle wall. make sure its not loose on the shaft.if it is then new dist will be needed

Hi, since you've replaced everything else, about the only thing left is the crankshaft position sensor. This is the sensor the computer uses to time the spark signals. Because this sensor is expensive, I recommend you test it first to verify it's bad before replacing. I have pasted test procedures below as well as replacement procedure in case it fails the tests. You will need an ohmmeter for the test. If you don't have an ohmmeter, you can buy one for as little as $10, or maybe you can borrow one. You will also need a timing light if you replace the sensor. Please let me know if you have questions, and thanks for using FixYa. Fig. Fig. 2: The Crankshaft Position (CKP) Sensor rotor looks like a small gear in the lower distributor housing- CRV and 1995 Odyssey models 7. Check and reset the ignition timing as outlined below. Fig. Fig. 1: The inductive lead of the timing light is placed around the No. 1 spark plug wire; and the light is aimed toward the marks on the crankshaft pulley. Fig. Fig. 2: The red ignition timing mark on the crankshaft pulley is lined up with the pointer. The two small notches on either side of the red colored notch represent the plus (+) or minus (-) 2° increments. The white notch to the far right is Top Dead Center (TDC)
TESTING CRV and 1995 Odyssey Models
CRV models: The blue and white wires. The resistance should be 300-700 ohms.
1995 Odyssey models: The blue/green and blue/yellow wires. The resistance should be 700-1,300 ohms.
REMOVAL & INSTALLATION CRV and 1995 Odyssey Models
To install:
ADJUSTMENT CRV and 4-Cylinder Odyssey Models
If equipped with an automatic transaxle, place the shifter in Park or Neutral. If equipped with a manual transaxle place the shifter in Neutral. Make sure to apply the parking brake and block the drive wheels.
Odyssey models with 4-cylinder engines: centrally located on the passenger side, under the dash. The connector has two wires; one is brown with a black tracer, and the other wire is red.
See Figures 1 and 2
The white mark on the crank pulley is Top Dead Center (TDC).
2.2L/2.3L Odyssey 2.2L models: 13-17° at 650-750 rpm
