1996 Ford Probe 6 cyl Two Wheel Drive Manual 110160 miles

We were hooking up a new stereo system into my car. Well long story short the fuse off the battery to the power wire blew. We discovered that I had fried the head unit. Well after that we drove the car around 10 miles to and from my mothers home. The car drove fine then. After we got back to the house and left latter to go to the store the car wouldnt start. Weve checked all of the fuses in the car as well as the fuel pump switch.

Please help we have no idea what we did.
