Replace the BCM today on my H2 with a new one programed to the trucks VIN, did the Passlock relearn directions as provided, truck starts up, all the bad electrical problems are now resolved but now the Viper Smart Start won’t turnover. When activated from either the key fob or app the engine cranks but will not start as if not getting spark or fuel. Use the key and it starts right up. I’m leaning torwards this being a program issue and wondering if anyone knows if Vioer will have to reprogram the Smart Start somehow.

 

Found this pdf which may provide some clues, might be worth a call to Viper
