Apparently the reasons of failure for 2 recent Long March rockets flights - not yet known till now - have turned up in a tender for insurance of the future launch of ZY-3-03! The 2 involved are Long March 4C/YG-33 on May 22 last year and Long March 3B/PALAPA-N1 this April 9.

Yes, they implied that LM-3B's issue was related to manufacturing quality of some pyrotechnics onboard but (I think) it's not referring to specifically failure of the ignitors for retro-firing stage separation rockets between 2nd and 3rd stage of 3B.

Seems like it's just one of the potential weak spots on LM-4B Y45 that was reinforced with added redundancy, along with more checks of pyrotechnics throughout the LM-4B rocket.

I'm more inclined toward the hypothesis of an ignition failure in one of the YF-75 engines on the 3rd stage.
