CAR STALLED OUT DURING DRIVING CONDITION. ENGINE TURNS OVER GREAT. WONT START.

1992 Dodge Dynasty • 100,000 miles

I have a 1992 Dodge Dynasty 3.3l with approx 100000 miles. We have had the car for under six years and the only major issues have been trans related.
I was driving to the store last week and the car cut out while driving at about 40mph. I pulled over and could not get it to restart.
Minor low level diagnosis showed no fire from the wires to the plugs.
-- Replaced the ignition coil --
The battery was found to be insufficient
-- Replaced with a 660cca battery --
Crankshaft position sensor was suggested
-- Replaced CKP sensor --
I have shot some carb cleaner just to see if it was fuel related with no change in the start up.
The car has had a cut out issue for almost six to nine months. It has always started right back up afterwards with no issue. The cut out issue was very intermediate and never showed any serious sign to what may have been causing it.
Now I have a no start condition and a limited amount of tools and funds. I have been told it may be the ECM or the PCM or the Camshaft Position Sensor. I currently feel that this issue may be above my pay grade.

Thank you for any assistance.

Scan for codes first and check fuses like ign underhood. If you have an automatic shutdown relay check that as well. Also some of those have poor connection at cam/crank sensors. So check those.

Ignition checked - coil was replaced with no change
crankshaft sensor replaced - no change
ASD relay is what I am going to track down and figure out. Hoping I see it in the junction box really quick,
i will report back on what I find later in the day.
Tnx for the input

Btw, the battery was replaced after the breakdown. So I am assuming the codes if any were cleared. I have a list on procedure and the codes list just in case.

I was able to get back over to the car for a few minutes.

The asd relay was swapped out with the ac clutch relay.
-- turns over great --
-- no start up --
-- confirmed clicking from old asd and swapped asd relay
--

i then attempted to pull codes per the turning key ignition off/on five times and hold on position with fifth turn
-- no check engine light --
-- no blinking of check engine light --
-- nothing from instr cluster concerning check engine light --
-- confirmed other lights coming on in cluster (check gages, oil pressure, and such) I am assuming that the cluster is working as it should considering I am getting feedback from other sources through the cluster --

i removed wiring harness from pcm (located on passenger side of engine bay)
is this the pcm location for this year, make, model?
I cleaned off terms even though they showed no signs of wear and tear of any kind. I blew out harness just in case some kind of trash. I seen none. I re-installed harness to pcm(possible pcm until confirmed). I attempted to re-start engine.
-- engine turns over great --
-- confirmed asd relay clicking --
-- no start --
-- no check engine light --

kinda stumped now.
Is there a way to bypass the pcm for a start up to confirm it being bad or not. I dont have a load of tools to do some of the necessary diagnostics with the electrical system. So I would need a backwoods approach to this, lol.
I fully understand that I will not be able to drive it even if a bypass trick allows it to start up. I am just trying to get this issue in one direction.
Is there any other steps that I may try or need to do to assist you in assisting me?
Thank you for your time as I am grateful for your input.

No you need th pcm, butyou can disconnect a sensor to see if it starts that would put you in open loop, stil go through pcm but would let something else be wrong on a code. What engine is this? Try these two tests: TEST NS 9A NO REFERENCE SIGNAL DURING CRANKING (DTC 11)

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION . For appropriate wiring diagram, see WIRING DIAGRAMS .

CAUTION: When checking for spark, Single Board Engine Controller (SBEC) damage may occur if spark plug cable is held more than 1/4" away from a good ground.

1. Turn ignition switch to OFF position. Disconnect distributor pick up connector. Disconnect coil wire from distributor. Hold coil wire a maximum of 1/4" away from a good ground. Turn ignition switch to ON
position. Connect a jumper wire between terminals No. 2 (Black/Light Blue wire) and 3 (Gray/Black wire) at distributor pick up connector.
2. Make and break jumper connection while checking for spark at coil wire. If a good spark does not occur, remove jumper wire, and go to next step. If a good spark occurs, perform TEST NS 9B .
3. Connect jumper wire between terminal No. 3 (Gray/Black wire) of distributor pick up connector and ground. While still holding coil wire a maximum of 1/4" away from a good ground, make and break jumper
connection at terminal No. 3 and watch for spark at coil wire. If a good spark does not occur, remove jumper wire, and go to next step. If a good spark occurs, repair open in Black/Light Blue wire. Perform
VERIFICATION PROCEDURE VER 1 .
4. Turn ignition switch to OFF position. Disconnect Single Board Engine Controller (SBEC) connector. Put DRB II in ohmmeter mode. Probe terminal No. 24 (Gray/Black wire) at SBEC connector. If resistance is
less than 10 ohms, repair short to ground in Gray/Black wire. Perform VERIFICATION PROCEDURE VER 1 . If resistance is more than 10 ohms, go to next step.
5. Using an external ohmmeter, measure resistance of Gray/Black wire between terminal No. 24 at SBEC connector and terminal No. 3 at distributor pick up connector. If resistance is less than 10 ohms, replace
SBEC. Perform VERIFICATION PROCEDURE VER 1 . If resistance is more than 10 ohms, repair open in Gray/Black wire. Perform VERIFICATION PROCEDURE VER 1 .

TEST NS 9B NO REFERENCE SIGNAL DURING CRANKING

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION . For appropriate wiring diagram, see WIRING DIAGRAMS .

1. Remove jumper wire. Place DRB II in voltmeter mode. Probe Orange wire in distributor pick up connector. If voltage is more than 7 volts, go to next step. If voltage is less than 7 volts, go to step 3 .
2. Turn ignition switch to OFF position. Remove distributor cap. Crank engine while watching distributor rotor. If rotor turns, replace distributor plate (Hall Effect pick up)? If distributor rotor does not turn, repair
distributor drive system. Perform VERIFICATION PROCEDURE VER 1 .
3. If voltage is less than 7 volts at Orange wire in step 1), check if voltage is zero volts. If voltage is zero volts, go to step 5 . If voltage is more than zero volts, turn ignition switch to OFF position. Disconnect Single
Board Engine Controller (SBEC) connector.
4. Using an external ohmmeter, check resistance of Orange wire between terminal No. 7 at SBEC connector and terminal No. 1 at distributor pick up connector. If resistance is less than 10 ohms, replace SBEC.
Perform VERIFICATION PROCEDURE VER 1 . If resistance is more than 10 ohms, repair open Orange wire. Perform VERIFICATION PROCEDURE VER 1 .
5. If voltage is zero volts at Orange wire in step 3), turn ignition switch to OFF position. Disconnect SBEC connector. Place DRB II in ohmmeter mode. Probe terminal No. 7 (Orange wire) of SBEC connector. If
resistance is less than 10 ohms, repair short to ground in Orange wire. Disconnect and reconnect battery quick disconnect. Perform VERIFICATION PROCEDURE VER 1 . If resistance is more than 10
ohms, go to next step.
6. Using an external ohmmeter, check resistance of Orange wire between terminal No. 1 at distributor connector and terminal No. 7 at SBEC connector. If resistance is less than 10 ohms, replace SBEC. Perform
you don't have a drbIII so you will have to usea avoltohm meter. Ican't find any cam sensor specs but check against a newone ifyou can and make sure the connection is good because those have been known to fail

The reply you left is chopped off in some spots. Could you re-do the procedures again plz.
Also, what sensor are you talking about that would allow the engine to catch and start up with error codes(OPEN LOOP)? I was under the impression that the crankshaft position sensor and the camshaft angle sensor HAD to be plugged in or the engine would not start. Could I do this before these other steps?
Also, I do not have a ohmmeter or test light available to me at the moment. Is there a way to test these components without the test light or ohmmeter? I am willing to do all the grunt work but I am in a tight bind with money and limited with tools. I may be able to borrow some tools at a later time but my contact concerning that is out of town for a minute.
Thank you again.

It's not chopped off just looks like it. Where you see the 1 then period that is end of ver1 you can unplug any snesor other than crank/cam sensors. Uno the coolant or maf see if it starts. If it doesn't yo need to do those tests.

Just re-read the steps and noticed these steps are for a distributor. I have a 3.3l - distributor-less ignition. "Six pack" ignition coil.
I am also tracking down an ohmmeter as I am writing this. Should have one by tomm(sun 9/30) hopefully.
Let me know what steps I can take with this distributor-less ignition and I will do my best. Trying to research in the meantime.
Tnx again

"ya know you never gave what engine it was so I just got it off a 2.5l see what happens when you don't give all the correct info?"

lol, original post in first sentence was "I have a 1992 Dodge Dynasty 3.3l with approx 100000 miles."

i understand that many people may not include info that is pertinent. I have dealt with that time and time again since I am in the IT field as of late. But be fair brother, don't accuse someone of something before you back up your own statements.

In any respect, I do appreciate that time you have put forth and I am very grateful for that. I will attempt to run some of those diagnostics you have provided. I will let you know of any outcome if you wish. If not, I will consider this thread closed unless someone else picks it up sometime in the near future.

Again, thank you for your time and valuable feedback.
