The fuel symptoms I have sound familiar to previous posts in this forum. Emgine starts fine cold and runs great at cruisiung speed. Once it sits (engine off) starts right up but soon after engine stalls. Seems like a fuel issue. I have ruled out electric (spark) etc. Fuel pump seems fine. Good pressure and fuel up to injector pump. Can hear injector pump clicking. Previous posts say check fuel pressure regulator. Thoughts, suggestions and/or possible diagnosis??????? Thank you.

TBI or MPI on the 1996 7.4 ? got a serial number? Definitely test the fuel pressure, as Scott recommended. Is this VST or cool fuel?
