My coolant reservoir had a crack in it and my serp belt was looking bad, so I replaced both and also the small 1/4 inch hose from reservoir. Went to crank and was sputtering, then outta nowhere shut off. Serp belt is right. Fanned the gas and got it cleared up so went around the block. It died on me. I fanned the gas and stopped and started it back home. M and S are flashing while hill decent assist stays on plus check engine is always on since o2 sensors were unplugged. I got the codes cleared and the M S LIGHTS are staying off but can't get it to crank and run right at all without fanning gas just to keep it running...
