Eric Posted November 19, 2023 Report Share Posted November 19, 2023 Hello, After changing intake gaskets, I reconnected battery and my Larosse will not crank. The DIC is blank and the only light on the dash when turning key on is the engine light. I checked the fuses to ECM/PCM and they are ok. Checked the ground to engine and it is ok. I believe I have either a power/ground failure to PCM but can't find a wire diagram for this 06. I checked each pin for voltage with key on but no voltage to any pin. Battery voltage is 11.6. Any ideas? Quote Link to comment Share on other sites More sharing options...
Schurkey Posted November 19, 2023 Report Share Posted November 19, 2023 (edited) 1. Charge battery. 11.6 = dead battery. Full charge should be 12.6--12.7 AFTER the surface charge has dissipated. May be 13+ volts with the surface charge. 2. Verify all fuses and fusible links. 3. Get a Genuine GM service manual set for your vehicle.
