I kno this is going to sound like a dumb question, but by chance did u not install the resistor box's needed for the DSM injectors? I had a friend with that problem because the iirc dsm injectors are peak and hold and operate differently than saturated.
resistor box from an old prelude was tested and installed so thats not the issue. found out my cam sensor isn't working properly due to heat soak. whole distributor is being replaced since the whole assembly is from my original engine. also my CKP died. which was a sensor that we re-used as well. so after replacing those few things I'll see if it still has issues and go from there.

What EMS are you using, and what is your fuel pressure?

using hondata s300. can't think of the fuel pressure right now but the tuner checked that when we were tryin to figure out the issue so its not that. I'm really thinking it was a spark issue. cause we couldn't find a single fuel issue other then the fact that injector DC was dropping. but if the ecu detects a misfire it cuts fuel and ignition as a protection measure.

we'll see how it turns out. got a full time job now and I should be getting a $700 paycheck on friday so I'll be able to get these parts and see if I can get her up and running again. then I can fix my few brake issues and enjoy driving her while I save up to mod the 240 a bit.
