It keeps shutting off on on me. I have changed the relay the battery the fuel pump and it still shuts off on me. But when I wiggle where the relay goes it is like if it is loose because it starts right away. Can you please help me?

Welcome to 2CarPros.

First, are you referring to the fuel pump relay or something different? If it is the pump relay, remove it and check where it connects in the relay box. Make sure the tabs inside are in good condition, not damaged, and not corroded.

Do that and let me know what you find.
