Hello,
I know that someone who put first post with support request is not well liked, nevertheless I would like to ask You for help, because I saw a lot of people in other topics with huge experience.
I read a lot of them, I made small progress, but still not problem is not solved.
My Honda 6G, sedan, 1.4iS Gasoline + LPG, D14Z2 has no spark.
Symptops were: one day I observed irregular work of engine (check engine start to blink). After few kilometers, I stopped, I kept motor running working on neutral and it suddently switched off. After this I cannot start again.
I found one high voltage cable broken. After this I replaced cable and broken Igition Coil Fuse (no. 9, 15A).
After this I cannot start the car. I have no spark. I have voltage on power yellow-black cable in the connector plug just before the distributor, but I don't have voltage on coil.
I dismantled coil, supplied directly with battery + bulb and looks OK.
Voltage "disappear" in HITACHI E12-303 module in distributor, but now I don't know if:
- module is broken
- module doesn't give voltage, because of something?
What I should check? I will be grateful for any support.
Thank You very much, I will check it, I have only one more short question (manual explanation is clear, but just to be sure, if I didn't damage earlier)
there is any sensor which could not give signal for ICM to give voltage for coil? - something like Hall sensor, or something different, which could impact for it?
As I said on the plug I have connection
Hello again,
Today I tried to check according to Your suggestions ICM.
Fortunately I discovered that fuse which was previously OK, was burnt, so I replace it.
After this I had the voltage on the coil, but now I suppose that coil is the rootcause.
I have TEC TC08-A and HITACHI E12-303 module.
I measured resistance :
on the primary => 1 Ohm (vs 0.6-0.8Ohm),
on secondary I received: 8kOhm vs 12-18kOhm
I additionaly disconnect wires from ICM and measured voltage between
+ and body ground - ~ 12V
- and body ground - also ~ 12V.
I suppose that for sure I should change the coil, could You just confirm?
And there is any recommended replacement if I original spare will be not available? I found on the internet:
IGNITION COIL
On the other hand I had one question - in the above manual there is information
to check voltage betwen body ground and BLU or WHT/BLU wire.
To be honest I didn't have blue wire available (in the attached photos) - could You tell me for what it is? (point 4) if it could be not available
And about point 5 - what does mean ECM/PCM Connector A? It is the connector plug just before distributor?
Yes, I checked for the spark after fuse 9 replacement, but still no spark.
Yesterday I received new coil (Magneti Marelli replacement) and I replaced it.
After this motor successfully started and it looks that problem is solved.
Just to add for any other people in future - I also measured resistance of new coil.
Primary - Old: ~ 1.0 Ohm, New - same (internal resistanace about ~ 0.2-0.3 Ohm) => so this on old was also OK.
but on Secondary: old - ~ 8kOhm, new - ~ 15kOhm.
Unfortunately I don't have idea, what was the root cause of it (I only found on the plastic housing of coil some places where it was a little bit melted, so maybe just lifetime of coil was end
