Hello, I have been troubleshooting this issue on my 1997 Lexus sc300 2jz NA-T build for quite some time now. I’m pretty new to this and i have been trying to figure out why my car will not fully startup. The car does fire over and over but i have not been able to find the real reason behind why the car wont start. I’m using the provided base map file for the PnP adapter provided for the emu black. I am also still using a dizzy and I feel like maybe it has to do something with timing since I’m getting fuel and spark. Any help is greatly appreciated!

This is very little information for people to help you troubleshoot. I am super new as well so I’m probably not a lot of help even with information but im guessing you have checked spark visually with the test outputs function. How are you sure you have fuel??? Do you have rail fuel pressure? Im guessing no dbw, if so, what settings do you need to account for that?
I suggest connecting, bringing up the scope and cranking a few times. Show that here. Theres just so many settings that could be interfering that its really hard to guess at anything. To give you an idea, Ive been troubleshooting DBW for months and it still does not work…and its just 4 wires.
Good luck!!!
Yeah, for some reason it cut off half of what I originally typed in. So far, I have confirmed both fuel and spark by visually seeing the spark and pressure going to my FPR. I am not using dbw so don’t need anything for that. ill upload my most recent scope below. ( its not letting me upload since im a new user ill provide the scope in a google drive folder) https://drive.google.com/file/d/1bNU96xBXy3vuLc2hlS_s0hs9p5sCwXXH/view?usp=sharing
