Having problems with your 1994 Ford F150 Styleside Supercab ?
Grinding or screeching noices on cold start - 1994 Ford F150 Styleside Supercab
Have you checked the conditionof your serpentine belt? If the ribbed side of the belt looks shiny, it has probably been slipping. It is common for a worn belt to slip and screech on startup due to the extra load on the alternator.
Usually screeching is the belt. It gets old, hard, and stretches. Also you have a tensioner that can weaken over time. To test if its the belt pop the hood and have some water handy that you can get on the belt/ It will get quieter for a minute when water is applied. When you have the belt off spin all the pulley and feel for smootness as they turn. If you suspect a bad pulley replace it.
