I can start my car it will run a few moments then shut off. Start it up again shuts off won't start again unless it sit for awhile. I replaced the fuel pump relay. Thinking fuel pump?

Hello, I'm Danny.

I would definitely check the fuel pressure. I would some how put a mechanical fuel gauge in the fuel line to test the fuel pump output. The fuel pressure p.S.I. Specification is 9-13 p.S.I. Let me know if you have any further questions. Hope this helps and thanks for using 2CarPros.
