Fuel pump sounds good when turning key on has a air swishing sound about thirty seconds then stops when key turned off sounds again. Coming from map sensor area.

Hey STRINGY321,

Did you replace the pump because it wouldn't start?

Fuel pump didn't run before but now does?

Have you checked to see you now have fuel pressure?

Can you take a video of the noise you are getting, might be easier to describe it that way.

Regards, Joe
