Hey, I have a 2015 Mustang with Roush Supercharger. Sunday I upgraded to ID1050x, DW 400 Fuel pump, and the spark plugs. Since then when I go to start my car it takes me 5-10 to get it to start. It just cranks while fuel pressure builds up in the lines. I called DW they said it’s a bad check valve, get a new one installed today and it’s doing the same thing. I can’t see 2 pumps in a row being a bad check valve, any other ideas what’s wrong?
Video of it.
