Check the ground on the engine block. Also check the starter itself.

Just got it to push start so i think it's the starter....the battery charged right up drove it for about 10 mins and got home then tried turning it off and back on. Dead. Same whine noise. Getting a new starter tomorrow. Will update

The easiest way to test it is,make sure the transmission is in neutral (youll run yourself over if it isnt) grab a long screwdriver,lay it on one of the large solenoid posts then touch it against the other large solenoid post.This will jump the solenoid and trigger the starter to turn over.If it doesn't turn over,the starter is bad or the starter cable is loose or bad.Its most likely the starter though,since push starting was required to get the car running & because its making a humming noise like you stated.

I haven't checked prices lately,but if youve got the funds,the 92+ 5.0 Mustangs came with a high torque mini starter which is a much better starter.Keep in mind,you have to wire the starter differently,at the fender mounted solenoid,if you upgrade to this starter.The 4ga starter cable gets relocated to the same solenoid post that the pos battery cable is attached to and a 12ga wire gets added that runs from the other large solenoid post to the starter. So if you decide to upgrade, be sure to wire it just like shown in the diagram below. If you buy the regular starter,leave the wiring as is,of course.
If youve got a Pull-A-Part locally, 94-04 V6 Mustangs are sometimes available,that you can grab a mini starter from,so if funds are low you can try going this route instead of buying new/remanufactured,but with any junkyard part you buy,you wont know if it works until you get it home and try it out,test it in the parking lot with some jumper cables or have it tested at the local parts store.It is a cheaper option though,if youre willing to try it.86-95 5.0 Mustangs are rarely,if at all,available at any Pull-A-Part Ive ever checked, but Ive had luck finding the 94-04 V6(3.8) models there on a regular basis, so you might have luck as long as nobody has beat you there already.I copied the following vehicle list from the junkyard hp thread which shows other models/years that the mini starter is also available on,so if you can't find one on a 94-04 3.8 Mustang,check the vehicles listed below.

It's the bendix drive on the starter itself. You can actually just repair that part with a kit from an auto parts store. OR just buy another starter. If the starter spins, the starter and the solenoid are fine.

But i still changed it cause this is what the old one looked like

Be sure if you have headers to replace with a newer model mini starter, and a heat shield wouldn't hurt.
