Question about 1990 Ford F150
This could be very bad, some things that could be fried: ignition module, ecm, voltage reg if it's external, I'm assuming it's internal as you have replaced the alternator.
The first thing I would do is turn on the ignition and go through the fuse block to make sure everything is OK. Then, put a mechanics stethoscope on an injector to see if they're clicking when you crank, if not, the ecm is suspect. You can also pull a plug wire off and use a spare spark plug to check for spark.
