Last time I drove it it shut off while coming to stop to park. Next day it turns over won’t start. Put new plugs, reset auto theft, still won’t. It is getting gas, pump kicks in, you can smell and hear.

I would also check the actual fuel pressure. Even if the pump works, it may not be proving sufficient pressure for it to run.

Fuel System Pressure

Key On Engine Off 41-47 psi

Is the check engine light on? If it is, can you give me the code?
