If you can get a code reader on the car, that might help. Most common causes for an engine to die right after starting are idle air control valve system, MAP/MAF sensor, engine coolant temperature sensor, faulty ignition coil, and maybe the fuel pump or its relay.

I used a code reader,nothing came up,my check engine light isn't on


The soot is a sign that the engine may be flooding.
