Hey My fellow dsm tuners ............Yesterday i decided to go and fire up my 95 gst (which has been sitting in my garage for 4 years) and noticed that i had no spark plug wires so i went to autozone bought new ones and forgot the order in which to place them so i looked in the tech guide found nothing, if anybody can help me out with this little dilema it would be great ..........

4, 3, 2, 1 <---- Cylinder Head.

4, 1, 2, 3 <----- Coil Pack

just so you dont do what I did,

edit: picture removed due to incorrectness, again... that seems to be a trend between me and spark plug wires...

 

[BaddAssGst]

just so you dont do what I did,

Was that a joke? Because you have it upside down.

It should be 3, 2, 1, 4 from top the bottom according to your diagram.

 

[Boosted98gsx]

Um, technically, it would be 1&4 then 2&3 and then back because we run on wasted spark.

shit, I was thinking about what I did in my car, not what your supposed to do. let me edit that.

/\ that picture up there is what I did. Ill delete it once I have the correct one up.

Your correct there but I was trying to make it as simple as possible for him.

Hello. First time posting...
Trying to help a friend out with her car, 1997 Eclipse. I don't know a thing about Mitsubishi motors.
Can anyone please tell me the firing order? What number one cylinder is on the block and distributor?
It has no plug wires in the car. I'm totally blind on this, could anyone help? Much appreciated.

4, 3, 2, 1 <---- Cylinder Head.

4, 1, 2, 3 <----- Coil Pack

 

[Fixxxer]

Sweet. Is this left to right as your looking at the motor from the front of the car?

 

[andymoraitis]

Nope, cylinders are right right to left (driver's side to passenger's side) from 1-4

Hope that helps,

Andy

 

[Fixxxer]

So...
Left to right on the head its 1-4.
Left to right on coil is 3,2,1,4.
?

 

[DSM_TSI_95]

No as you stand in front of the car your cylinder will be like this
4-3-2-1 cylinder
4-1-2-3 coil

Thanks for all of the help guys.
Troy, I appreciate the diagram you came up with.
I've never worked on a 4 cylinder motor, first time for everything I guess. It's running better than ever.
I'm going back to my small block Chevy motor.
Thanks again!

 

[marcus95turbo]

how is it going iam a newbie to this site i have a problem umhh my 95 eclipse turbo has spark to pistons 2 & 3 not 1 & 4 i need some advice from you guys i checked my coils my connections and other basic things that you can spot on your own checked my injectors wires for any cracks i bought a pcm but does the same thing a mechanic just overhauled my 4g63t dont know what the problem is anybody with advice welcomed thanks for your time

Try swapping in a different coil pack. The firing order is 4-1-2-3, 1-4 being the same coil and 2-3 being the same coil. I had one coil go bad on my coil pack so I bought a coil on plug. But in your case just swap in out for a known good one and see if that works.

 

[luv2rallye]

If you actually really tested (or swapped) your coils and they are good, next test the power transistors. Here's how:

(Note: The pin numbers for the following are the ones on the power transistor side connector – not the ones on the harness side connector (for which I put the wire color in parenthesis for reference).

Unplug the power transistor 8 pin connector.

To test the power transistor for cylinders 1 & 4:
Connect the negative side of a 1.5V battery to pin 3 (black wire) of the connector. Connect the negative side of a 12V battery also to pin 3. Connect the 12V battery positive to one side of a 12V light bulb. Connect the other side of the 12V light bulb to pin 8 (black/white). The light should not be on. Now connect the 1.5V battery positive to pin 7 (black/blue). The light should go on.

To test the power transistor for cylinders 2 & 3:
Connect the negative side of a 1.5V battery to pin 3 (black wire) of the connector. Connect the negative side of a 12V battery also to pin 3. Connect the 12V battery positive to one side of a 12V light bulb. Connect the other side of the 12V light bulb to pin 1 (blue/black). The light should not be on. Now connect the 1.5V battery positive to pin 2 (brown/red). The light should go on.

Is there a difference in firing order from Gen1 and Gen2 engines?

 

[92awddsm]

No, both are 4123.

 

[Slippi84]

Are the 90 coil packs diffrent from everyone else's??

 

[yaelster]

... I'm going back to my small block Chevy motor. ...

Sounds like a torquey guy.

 

[Shogunstang]

Is there a problem runing the car in 1234 order than the 4123 order?

 

[GSX93DSM]

Are you running that firing order now?
