2023 fall didn't start once. Took 30 seconds then fired up. Continued to increase in frequency until just didn't start anymore. Bcm lost communication so I unplugged elec. Suspension module. Unplug OnStar for code also. No codes except b2961. Anyone know where key in circuit is grounded? Wire diagram for key switch ? Wondering if grounded in dash. Have dash cap off.
02 Yukon Denali 6.0 key in ignition volts zero. Doesn't see key. Crank, no start, no spark. Only code b2961.
