OP never responded but I do have a question I recently lost fuel to cylinders 1 and 3. I confirmed spark, but haven’t checked pulse with a noid light. 92 LS400 so group firing. Are these even in the same group? Let me know your thoughts on how to proceed with the diagnosis steps.

Are you referring to the voltage of the two pins that attach to the primary windings ?

Yes. All the pins are correct. It’s an intermittent fuel cut, so it’s going through fail safe deactivation. Why would the signal be intermittently lost if it’s not grounding out anywhere ?

I tore the entire harness out of the engine bay and had a look through of everything and didn’t find anything suspect, additionally i also have the igniter mount attached to a dedicated cable that is fastened to the body from the chassis. I pulled some igniters off a new arrival at my local pull...

i replaced the switch i was using and now it’s charging at a solid 13.9v

Update: Replaced coils because the primary windings were a little high. No change. I found a video on youtube on how to test these igniters and it appears the transistors are working. I really need some help guys. Loosing a ton of motivation at this point…

Update: -New spark plugs -Plug wires - Alt is charging properly Codes 14 and 15 are still present. Even tried a new ecu and no changes. Is there a way to test the ignitors? This misfire is driving me up a wall. It starts up absolutely beautiful when it’s cold and starts to miss only a few...

Directly on the battery with it idling, and under load. Got it charging now (12v switch was bad) and now it’s running much better, but still missing ever so slightly. Gonna check codes again tomorrow.

One thing I discovered today was that while the engine is running, i’m only getting 11.7 votls at idle. Under load there is no change in voltage.

As far as my knowledge is concerned when code 14 and 15 are triggered, should this kill power to all 8 injectors? Every code 14 and 15 thread i’ve read have all had a no start condition. These are the only codes i got. I’ve pulled every spark plug and injector out one at a time and each time the...

Seeking help from the wise I have a 1st gen 1uz in my 240sx on a 89661-50032 ecu (26 16 22 26 plug) with the KA Transmission. I’m chasing a random miss that worsens as engine gets to temp. The only two codes i’m getting are 14 and 15, but the car runs??? Things i’ve done: -All 8 injectors...
