wont start but turns over strong???

ok replaced the coil, getting spark (I think), getting fuel, smell the gas no issue, just wont start! Its getting very frustrating! I am somewhat boggled as again a few days ago went out filled up with gas no issues no warning just now no go! Could it be the orange box on the electronic ignition upgrade??? I never had issues with one before on my other Barracuda, but one never knows! I may just have to look for a place to send her out to, anyone know good place here in Wheeling, Mount Prospect, Il.???
