How much does it cost to fix my squeaky belt or pulley? on 2003 Ford Taurus

It happens when i start my car and only when i press on the gas. It happens every time i start it.

Do yourself a favor, pop your hood, grab the belt, see if it moves up and down. It should not move more than half an inch in either direction. If it moves more, Tighten it(adjust). Look for cracks. If it looks good, go down to your local auto parts and by a can of Belt Eze or other. Spray some on the belt. Start car. If noise is gone, Then you will know for sure if the belt is bad. Checking for a bad pully, Remove the belt, turn each pully fast by hand, listen for noise. At least you will know for sure what your problem is. Goodluck, Help4u
