2019 Duramax No crank No Start

Troy Walter · February 6, 2022

Well ill start by saying,I replaced all 8 injectors with Denso Factory spec new ones,i tried to start truck when i competed this job and got maybe i couple of cranks from engine and it shut.off and would not crank anymore,i now re-programmed the injector flow rate to match new injectors which I didn't realize I needed to do when installing identical injectors. Now after leaving no power to truck overnight to reset everything all I'm getting is a single click noise when I release ignition I get the click again maybe 2 seconds later. Any help or advice would be greatly appreciated.
