Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.In order for the engine to start and stay running you need good spark to the spark plugs, injector pulse and proper fuel pressure. When it shuts down can you check and see which one of these you are lacking and post back with the results and we can work from there to try and get this resolved.
Okay post back when you can and we can work from there.
Something is being over looked, if you are sure you have good spark, injector pulse and proper fuel pressure the engine should start and stay running.
Okay, that would be the next step, go back and recheck each and make sure you not lacking one or the other.
