Basically I'm just replacing a GM HEI I've been using with the Terminator X Stealth for awhile now. All new components, i bought the Hyperspark coil and dizzy from Butler ( I buy alot from them with the poly gear installed which is recommended for Hyd Roller which i have. Hyperspark 2 ignition box and adapter from Holley. Just got the EFISystems Pro adapter because I want to keep using my tach as well. I just verified I'm certainly getting spark. Reached out to Holley, asked me to confirm the LED lights on ecu are reading correct, they are. Light on the ignition box stays Orange when cranking which I believe means no signal from ECU from what I've read. I'll try reaching out to EFi Systems I've bought from them in the past Agree, great dudes. I've been doing alot of this troublshooting with the fuel pump relay out so I'm not constantly dumping fuel thx.. I'm actually digging out my 850 double pumper now just in case. This is getting crazy.

Ok. I found the issue. The distributor pigtail was wired incorrectly from Holley. After correcting that I got RPM signal. Engine fired up for a minute then stalled. I wasn't expecting it to fire right up with dizzy at 0 TDC like they call for. Normally my idle timing is 24-26. I'm going to mess with that today, but at least I'm making progress. Thx again.
