A few days ago my car was running just fine, then it suddenly shut off on me and when I turned it back on it would vibrate the entire car violently. I managed to get it home before it completely shut off. I changed the ignition coils and spark plugs recently, I’ve also cleaned out the idle control valve and changed out all the fuses. I also checked fuel section and it still won’t stay on. Starts but stalls out or doesn’t star. odm2 has no codes.

hello,

You have to check if spark is present, injector pulse and fuel pressure, also it could be from security system prevent from starting use spare key and try to start. also it can be a big vacuum leak.
