4 pin ECU/2 terminal ballast conversion I am assuming. In your driveway get hot to where it wont (re)start & have a helper crank it & you under the hood see if you have voltage at the blue/yellow wire/terminal on the ECU pentastar connector and at the coil positive primary terminal. Work FAST while everything is hot for a valid test. This'll get us started.

Check for bad connections as mentioned but don’t overlook the need for the ecu to have a good ground too. Guys all the time change out an ecu and don’t clean the mounting area or run dedicated ground to it. I’ve actially put “bad” ecus back on cars for people and they run fine for years when the corrosion builds up again on the new one.
I want my fair share
