I need the code for the 6 pin plug that this distributor have to know if that's the problem to no start engine.
The distributor is brand new.
The problem is that it won't start i'm going to make a test to the entire system primary and secondary circuit, but I need that plug the way it goes to diagnose the problem. If you have the diagram code for this plug please let me have it, this car is so special, because the owner of the car is a cancer patient and need the car to go and get her chemo treatments. Thanks a lot for the help.

Hello and thank you for using 2CarPros. Unfortunately there is no specific code we can give you. The power train management should post a code if there is a fault. Have you checked for spark, fuel pressure, and fuel injector pulse? How is the compression? Looking at picture #2 looks like your missing the connector for the distributor and the harness does not look to healthy either?

So let's start with what fuel pressure is, do you have spark and injector pulse? Let us know please.

That's the diagram that I need, for that connector.

It sounds like you have good compression. Here is the engine wiring diagrams you requested. Check out the diagrams (below). Please let us know if you need anything else to get the problem fixed.

Hello. You send me the diagrams for the 6pin connector in the distributor, I make the changes, but I still not have current on the spark plugs. I check the pin for current and have voltage from the battery and return.
It would be possible that there's another diagram for that car?
I send to you the vin number of the car, for a maybe.
Vin number mazda mx3 1994 1.6l dohc

If note on the video the rotation is counter clockwise.
On diagrams of the firing order I found it says that the rotation is clockwise. I check the cylinder number one and the rotor. Piston number one on top death center and the rotor match with the piston. The spark plugs cables are right 1-3-4-2. In that order, but at the same rotation of the rotor.
I think, maybe it's possible, that their is another wire order for the 6 pin plug? Let me know what you think and found. Thanks.

In the diagrams the rotor does turn clockwise so don't worry about that. Double check your work using the wiring diagrams above it is a six wire. Use this guide to check your work:

Only some of the codes make sense, have you tried a used computer? Also did you check the system grounds?

I need to do that test, if you can help me with that I appreciate. That's one of the problems that I have. I think I don't have ground on the ECU, ECM, etc.
I don't have current on the spark-plugs. Give me light with this problem.

Ignition distributor 6pin plug

Mazda mx3 1994 1.6l 4cil. Dohc natural aspirated manual transmission
Vin# : jm1ec4359r0319261
Ecu/ecm/pcm # b6df 18-881/18-881a

Wht/red = 12.3v
Green = 5.01v
Blk/grn = 0.01v
Vio/wht = 5.01
Blk/org = 0.03v
Org = 0.03

No current to the secondary circuit.

Computer plugs 22pins 26pins

Wht/red = 12.19v
Green = 0.41v
Blk/grn = 0.01v
Vio/wht = 0.73
Blk/org = 0.00v
Org = 0.75v

Observation:
There are variation on the reading of pins.
Check grounds: i'm going to check the grounds again.
Positive cable from battery to inside of the passengers cabin, passing through the firewall by a hole on metal without protection. The cable is damaged and have contact with the metal of the firewall. I repair it
The relays are working properly.
At this time the check engine show only two codes #35 and #41. I make the repair for the other two #4 and #9.
I'm going to change the coil, because for me is strange that there's no spark at the spark plugs.
I'm going to repair the other two codes, but i'm going to change the coil.
It's that or for the readings of voltage I made there something wrong with the ecu, ecm?
Is the same diagram for the manual transmission engine?
If you have any other suggestions, i'm open to receive it. My mind is open for other points of views. I'm learning.
Thanks.

Hello Ken. I have the same ECU that was on the car. I put dielectric grease before I put the plugs, I have a problem with that? I checked the wires with the diagram and they're okay. I measured the volts, are this measures correct?
Whitered= 12.2v
green= 5.02v
black green=.03v
violent white= 5.02v
blac korange=.06v
orange=.04v
it's the possibility of a bad coil?
I still don't have spark.
What you suggest me?
Thanks for your answer.
Att. Juan Marin
pd.
If there a possibility, that in this diagram the engine is turning clockwise and mine turn to counterclockwise if the wires are going the inverse?

Do you mean you don't have spark from the coil or out of the distributor? Is the coil getting pulse? Check this guide out and report back:
