Starting problems, keeps cranking but no start up Options

[Tumult5sfe]

I had to do a head gasket some time back. put everything back together and went to start it but the battery was dead...so i slapped the charger on the thing and poof, my one ground wire that leads from driver side inner fender to engine went up in smoke. now the damn thing just sits and cranks all day long, i get plenty of fuel, not a strong spark but there is spark, and pretty much thats it.
so does anyone know what i may have to do? i grabbed another ecu thinking i cooked it, replaced the ground wire, and a few other odds and ends. also, when i turn the key off my fans kick on and the temp gauge pins hot, and they shut off when i flick the headlights on and off. Any help would be amazing.

well my bright brother decided to throw it on jump start on the charger right away and i think it just overloaded the system. odds and ends being, distributer, wires and plugs. i also replaced the ignition switch and the ecu start-up relay because i wasnt getting any kind of check engine light in the gauge cluster(thinking it may not be getting signal one way or another). so what do you think? wiring harness swap?
