Default 5.4l Swap Mustang Done, But new motor Wont start? Video
Just finished my 4.6 to 5.4 swap and the motor wont start. Everything is connected and I double checked. Could it be bad gas as it has been sitting since February?, Could it be the injectors. It seems likes its not getting fuel. Anyway I don't know what to do next.

(Engine from an 03-F-150)

I put a video up of it turning over if that helps.

Use the schrader valve on the fuel rail and see if you have pressure while somebody turns it over.

I lifted the fuel rails up and it sprayed out fuel so I know I am at least getting fuel to the injectors.

Only did it to verify I had spark. That little bit of starter wont hurt anything.
