T-2 No Spark
 

Im not getting any spark on T2. I checked with 2 other trailing coils that i know are good and still nothing. I checked the wiring from the ECU to the coil and its fine. The car will start and idle. I pull the plug wires at the coils and im getting spark on L1, L2, T1 and nothing on T2. Anyone have any idea whats going on.

Have you changed your plug wire? If you did, its gotta be a coil problems, i dont think the wiring is for seperate parts of the coil, i remember mine had 2 wires, but i dont think 1 was for each T side.

I can try a new plug wire for T2 but im not getting spark at the coil or at the plug. does that make a diffrence?

How are you testing spark at the coil? Im stupid and messed it up. Are you sure you have a working coil?

when the car is idling im getting spark on L1,L2,T1 but not T2. Im checking it by pulling the spark plug wire from the coil.

Have you tested your ignitor?

I tried another coil that i know is good and still same issue

So it may not be the coil. Did you test your ignitor?

how do i test the ignitor?

What microtech do you have?

Lt8s

if i were you, i would jsut swap out the ignitor for another. They are a dime a dozen.

update.

swapped trailing coil for another one that im sure is good. Nothing
pulled the CAS to see if the dimple was aligned with the nipple on the casing. Nothing
Swapped CAS for one that i know works. Nothing
Changed plug wires. Nothing
Any other suggestions?

Video coming soon.

anyone?

Same shit diff smell
 

Im in the same boat no spark on Trailing 2
standard motor and ECU

all i heard was a backfire 1minute into warming up after changing a battery and now cant start and no spark on T2

have i rooted my ECU?
cheers fellas :fingersx:

After a tow start still no start
spark on L1 L2 T1 but not T2
charged battery
65,000klm good comp
Factory setup
also changed the coil to another and still the same issue no spark on T2
what can it be?
is there anything else i can try to start this puppy
other than set it on fire 1 !
cheers all

i had someone tell me that it was most likely an internal problem with the ECU and i was going to have to send it back to microtech to have it tested and repaired

Its only a standard ECU

Well than get another stock ecu. If its a stock ecu, we cant really help you here. It could be anything from your wire harness being old and cracked, to your ecu failing.

Cheers
got it started and also found a vaccum leak wich was preventing start up
once startup is active there is no probs with idling just lack of power
it seems that its running but does not run that well due to no spark on T2?
bad ECU is my best geuss
cheers all

got a reply from microtech.

"Someone has changed the spark trigger to negative.It should be set on +MAZ when using the 13B coilpacks"

ECU should be here thursday.

I kind of having the same problem !!!

The car was working perfectlly fine. Store it for about two months then the L1 and T2 do not work !!! I didn't change anything as far as computer programming.

I have checked the connection its fine. the coils are brand new, duble checked them and they are good.

checked the ECU it is working no errors and the connection on the MT seems to be working !!..
Don't know what to do.????

how long did it take to send it to Microtech ?? and get it back ??

Thanks guys.

7 days travel time
about 12 days of them having it ( depends on there woark load )
7 days return travel time

Shipping from FL was about 85 dollars

Sooo.. total was 26 days !!! Damn.. that Alot.

tell me about it. Thats if it gets here on thursday like they said.

CHECK connections / crimps etc.

talk about an good day. the microtech came back today.

^^^ Not Working ^^^

So is that the normal sound of this motor? I have the 13b N/A in my Rock-Crawler and when it runs it sounds just like that one. Not being familiar with rotarys I figured I had something wrong since it seemed to idle quite high and had that miss in the motor. I can hear it in your video, but I guess that is normal? Even the exhaust sounds just like mine. That is great :icon_tup: Very healthy sounding.

Congrats on getting it fired back up. I am still working on mine (when I get the chance of course :uhh: ) after it stopped working on the trail in the middle of nowhere.

congrads.

tell us how is it ?? are all of the coils working fine ??

Everything is working fine and i actualy get to drive it a little now. Im in the process of putting the MSD's on now before it goes back on the dyno for the final tunning. If everything goes well it should be tuned by the end of next week. Ikeep you updated on the numbers.

Allright, good luck :) who is tunning your car ?

This Saturday. Lopez Racing in Miami
