Would yours smell like fuel when you tried cranking like in the video?Is it still on the factory camshaft position sensor or an aftermarket replacement? Mine did like in the video, or as you said sometimes catch, sputter, then run with an aftermarket CMP sensor. Put an OEM one back in and not a problem since. I drug my feet on swapping, even did a fuel pump and pressure regulator despite knowing aftermarket sensors are garbage in these. At least I've got new parts on the fuel system now. LOL.
