Spark plug troubles

[AKron]

I bought a 94 Ranger with the 3.0 vulcan and drove it home, the engine was shaking alot and there seemed to be a loss of power, I thought it might be misfiring because one of the spark plug wires was sparking. The guy I bought it off said it needed new wires and that would be fixed so i decided to just get new plugs too, when I replaced the plugs and wires the shaking stoped but it started kinda hard and had even less power when I drove it home it had even less power. The next day I started it and it stalled out when I put it in drive. I looked up the firing order and found the wires were out of order but Im pretty sure I put them on the exact way I took them off, so I put them right and checked over the order a dozen times but now it wont start at all. Is it possible that the wrong wires are on the wrong plugs and that could be the problem? If not what could the problem be?

p.s. the plugs were Champion Coppers and the wires were Duralast 8mm

here is the correct firing order. double check this is how you have it. also how did the distributor cap and rotor look?
