Starts but stalls after few seconds

Hi and thanks for using 2Carpros.Com.

It sounds like you have a fuel delivery issue. I need you to first check fuel pump pressure. Here is a link which describes the process in general:

The first picture attached indicates the manufacturer's specifications as far as pressure. I am not sure what size engine you have, but the pressure is the same for both options.

Do this and let me know what you find or if you have other questions.

Take care,
Joe
