Looked around and didn’t see anything specific on this. I have a 95 ls integra that’s b18c1 swapped. I’ve been driving it for 6 months no problem. Now it won’t start. The motor turns over and almost tries to start but dies almost instantly. If a miracle happens and it does start, it runs and drives perfect. I have a hondata ecu that I got tuned a while back, it runs a little rich but that’s about it. But If I hook up my original Ls ecu it starts up first try but because of the differences in motor doesn’t run well so I can’t drive with it. I bought a new jumper hoping that was the problem but that didn’t change anything. I have fuel and spark too. Has anyone else experienced this?
