TBI Fuel injection woes!

Well. Been a trying road lately with the TJ, but I finally have gotten it fixed! Just to refresh - I fuel injected the SBC that was in it when I purchased it. This is an older SBC with a quadra-jet intake. The thing was sputtering upon acceleration and under a load. I changed the adapter plate, gaskets, fuel pump, new fitting into fuel tank for 3/8” line(the one in there was like a 3/16”) and the distributor. All of this still did not fix the issue. So I pulled the little flat electrical thing-a-mabob (turns out it is the electronic spark control module, aka ESC) off of Zachary Smith’s jeep and voila! Problem gone-and runs great! $60 part and like 20 hours later of troubleshooting! Wish the darn thing would’ve thrown a code!
