My automatic transmission car is having difficulty to pull forward

Parts cannon????? what is that?
its old, and my 88 was worse. (french EFI injections)
Renix MPI on some, can be painful. OR is SBEC ECU.
well first ever get the service manual> I have them.
the ECU is OBD1, the dealers lost the old 1992 scan tool.CALLED DRB-II (or it scares them, OBD1 tech long forgotten)

or beat it to deathh DRB, 31 long years of uses. amazing facts. that.

if you pulled that DIZZY , you just lost injector timing
you did all that and not check , spark first. or compression>?
those 2 tests are first, always for sure ANYTHING 31 years old.
we use tools and do the tests and let the truth WIN.
guessing is crazy expensive and worse putting on new parts or old or bad parts on the engine or doing it wrong
btw the crank sensor put ON WRONG this engine wrecks the sensor and for sure a used sensor, wrecked put back on and not PREGAPPED. per the factory service manual , i Have.
no sure if yours sensor has a pre gaping kit new. for CKP

TESTING 1,2,3, wins the prize using test tools and methods.



check compression first on all for and all will be a 150 psi and equal done battery fully charged, and throttle open. so it gets air to pump testing a $20 tool , and test DIY.
next it the 100 year old test, called testing for spark using new test spark plug gapped to spec. and cranked. test all spark plugs
and the DIZZY wires are no good 31 years old. HV wire set. x5
at end of spark HV wire, add a test spark plug
ground spark plug metal outer shell top engine metal (ground)
crank and watch (a 2 person test) do all 4, engine will not run on 3cylinders or less.


the CKP sensors the flywheel/drive plate marks.
CKP modern name was back then CPS. named. so same.
if some one messed the m/t flywheel the CKP sure can fail

the ISC on these cars love to stick closed and no idle air is present. so 5%throttle start the engine via right foot pushed a tad.
does it? it loves to gum up.
the fuel pump has ballast resistor, that if blown fuel pressure is zero.PSI forever.
common fails Im talking hear.
I just do the tests , if you lived on my block, we'd have it running
or know for sure why not, I have scope here and all tools to do it.
this jeep like all jeeps have ASD, automatic shutdown relay
this relay is 100%ECU controlled, it shuts down
if ECU senses bad spark or fueling errors or any kind shorts and overloads of DC power to injectors or spark coil.
this relay is just fire prevention relay (a far better name)
or more simply it even checks this relay for bad.

to get spark ? the CKP and distributor CMP sensors must be good
firing order must best correctly and timed by you.

SOME brands of CKP are best avoided. buy SMP or NGK/NTk
brands,. some sold have gaping stick on gasket to the end that is a pregapiing device, one time use;. 2nd time the sensor is wrecked.
watch out for tricky CKP sensors. 3wire, it is.

Rules :
"Base ignition timingis not adjustable on any 2.5L,4.0L or
5.2Lengine.Base ignition timing and timing advance are
controlled by the PCM".+ CKP
the distributor timing is only for injections on this engine class.
(steps installed dizzy)
"Installation(2.5L & 4.0L)
1)Position distributor in engine.Ensure"O"ring is
properly seated on distributor. Replace"O"ring if cracked or nicked.
Carefully engage distributor driven gear with camshaft drive gear so
when distributor is installed properly,rotor aligns withreference
mark.
2)Install distributor cap. Check all highten sion wires for
good connections. Install hold-down nut.Connect cam shaft position
sensor wiring harness connector"

now the smoking gun words from the OEM manual 92
CKP /CPS ,installs

Installation (2.5 & 4.0L)
To install, reverse removal procedure.Use only proper
mounting bolt. Any other replacement bolt will cause improper sensor (the bolt is a custom shoulder bolt)!!!
alignment.On Wrangler with 4.0L engine and automatic transmission, or swaps.
ensure paper self-adhesive spacer on end of sensor is replaced if old
sensor is be in gre used. Paper spacer is used to set proper depth.Once
engine is started, paper spacer wears away!!!!
what engine is actually in in any old car, IDK, but this CKP facts can not be ignored. or spark will fail hard.

RECAP
check compression 150psi is common , done right.
check spark and for timing correct and firing order correct
order: 1-3-4-2 at dizzy top and 4 spark plug set.
rotor spins CW, clock wise.

check coil wire--distributor /dist cap

Sounds like a bad distributor. Had you pulled a spark plug out you may have found them wet with gas after cranking. If they are wet the crank sensor is working since both injector pulse and coil pulse rely on crank signal.

The distributors are known week points in the ignition system and used to be common when theses cars where still on the road. A reman will run you $250 U.S.

Pull a plug wire and spark plug. Put wire on plug and hold with INSULATED pliers against the block, where you can see the spark. Have a helper turn over the motor while you watch for a BLUE spark. if no blue spark but yellow or orange, then you don't have enough spark to fire. It is also possible you have a bad distributor coil, which is mounted inside the distributor. It's kind of involved to change, but possible. Let me know what you find and I'll try to help from there!!

So depending on Engine size, you either have 6 spark plugs or 8. The 6 cylinder doesn't have a cap and rotor, so just plugs and wires. The plugs are a 5/8 or 16mm socket. It is a special socket that has a rubber cushion to try and not break the plugs when removing or installing them. Regardless of 6 or 8 cylinder, you want the car to be cold for this. You grab one spark plug wire at a time, twist it back and forth, and pull straight away from the spark plug. Sometimes this is easier said than done. You want to purchase new plugs and wires, and if your car has a cap and rotor, you will want to get those too. I recall the '93 Z28 has a very expensive distributor cap, over $200 so maybe don't change that. The better brand of plugs come pre gapped. AC Delco is a great brand for Chevy. You want to put antiseize on the threads. Unscrew the old one, then install the new one. My favorite tool when doing this is a 6" wobble extension, as it seems to help with most plugs. You can take a piece of vacuum tubing 1/8" and stick it on the tip of the plug to help install the plugs without stripping out the threads in the engine cylinder head. You can remove one spark plug wire at a time and line it up for length with the new one in the set you purchased. Put Dielectric grease in the boot that goes on the spark plug end. Don't put it on the other side (Coil or distributor cap). Although there are many filters that can be involved in a tune up depending on the mileage of the vehicle, the biggest difference in how a car runs typically is spark plugs.

incorrect timing, tune it up, new spark plugs, wires, distributor cap / rotor, faulty coil, check transmission fluid level, change fuel filter, make sure spark plugs have correct gap, very important. when is last time air cleaner was replaced ? do it.

change one spark wire at a time on the distributor.buy new set of spark plugs wires remove them from box.match old wires with new wires to use the correct length to each cylinder.now if you need to change distributor cap.mark location distributor cap.number tag plug wires on the distributor cap so you can remove plug wires on distributor cap so you can replace cap and rotor and put wires back on the distributor cap in correct place.remember change one plug wire at a time so you wont get confuse.

· Open the hood and remove the bolts that hold the engine cover in place, if your Dodge comes with an engine cover (depending on model and year). If so equipped, pull the cover off the engine.

· 2

Grab a spark plug wire by the base of the wire and pull the wire up and out of the engine. (You may need to wiggle it back and forth while pulling up on it to get it out of the engine.)

· 3

Trace the wire back to the power distributor and pull the spark plug wire off the distributor. Make a note of the plug orientation.

· 4

Install the new plug wire in the place of the removed one. Match the new wire with the old one to make sure they have the same size. Press the plug wire over the distributor electrode and onto the spark plug firmly, so that the ends are secure. Installation is the reverse of removal procedure.

· 5

Repeat the above procedure for all the other spark plug wires. It is best to change all the spark plug wires at the same time.

could just need a tune up,you could also pull of the distributor cap and look for oil intrusion, if there is you will need to replace the distributor

Hondas have problem with ignitor in distributor that overheats and shuts off spark momentarily. then car will restart and shut off some time later.

Wouldn't hurt to change wires anyway if old, especially if new plugs were installed. Get the most out of gas mileage that way!!!!!!!!
