1991 Ford Bronco V8 Four Wheel Drive Automatic

i just bought a 91 bronco 302. My brothers battery was dead so he tried to take mine out while running and put his in to charge it up a bit, he got the neg hooked up to his battery and when he touched the pos cable to pos terminal truck shut off. Now it will only turn over but wont crank. Checked all fuses in cab but no luck. Any ideas

Something got fried for sure-Do below if its cranking over and will not start.

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
