2020 L84/8L90. Return line fuel pump. 80psi at regulator and 2100 at FR. Reading 150ish cranking RPMs and 12V while cranking. I have power/reference at coils and cam/crank sensors. Pedal and MAF installed. I am not seeing spark when I pull a plug. I’ve check every connector and ground. VATS disabled. Desperate for help. Thoughts? Thanks in advance
