2015 GMC Yukon XL Denali 6.2L No Start, Cuts out, Stall
Posted to GM Driveability on 1/3/2026 8 Replies

This truck will start for about 2 seconds and putter off. Customer says it was running intermittently poorly, and ok, but became a no-start. No codes. Acts the same with MAF disconnected. Fuel burns, will not run any longer when adding starting fluid....
