    Default Starts runs 3 seconds and stalls.

    2005 Supra launch. Starts right up every time but shut off. It’s starts easily and sounds perfect. Seems like something is simply shutting off engine. Messed with cut off switch but it seems fine. Any ideas?

    Check the fuel pressure during start up.
