Re: screaming sound starting engine
Most likely that alternator/AC/auxiliary belt.
Immediately after an engine start, there is a huge electrical demand on the alternator, and demand = belt drag.
If you have the AC on as well, that will put additional strain on the belt.
While it's making the noise, you can check it is that belt by squirting some water (not WD40!) at it. If it quietens down, it was that belt.

If the crank pulley is a dual-mass type, it could be the rubber starting to delaminate.
