    Yet another prolonged multi-week thread without resolution. I could have "found the issue" in my shop in under 30 minutes. This agony is approaching 30 days.

    XB coils are "singular" in construction. The key switch relay feeds them 12V....the ECM via secondary ground signals them. The ECM can only differentiate between supplied signal to "front" and "rear" coil sections via ECM ground....NOT thru the 12V source. Hence, stored active/historic fault codes #24 & #25. You'll likely have them and should be cleared out.
    You do NOT test these coils with a "spark tester" device...whatever that is. You test them as I've mentioned on here 2X in the past 2 weeks. CENTER POST---12V source........LEFT AND RIGHT POSTS---ECM pulsing ground signal. Any other "test" reveals nothing.
    You removed the wiring harness plug....the primary and secondary circuits dumped their stored voltage "to atmosphere"....you reconnected said plug and motor fired. Perform a proper "12V test light" procedure as per what I've posted on here...clear codes 24/25 if present...check coil wiring harness main feed for chafing in the vicinity of the TB assembly (known problem)...replace coil.

    Hey John... Don't be like, plagiarizing me n' stuff




    You told him, I told him, you told him again. Not sure what this is gonna take. Maybe he'll look at the plug for awhile and then post about it, before asking again.
