1990 Ford Thunderbird Spark plug problems

I gave my car a tune up, but I spaced out and took of my spark plug wires and didn't mark where each came from. I bought a book but it really hasn't helped get them back on. I put them on and my car turns over but dosen't start. It was running fine before, but it was way over due for a tune-up any Idea what could be causing my problem. If its the wires on the wrong post on the distributer cap please I need to know what goes where.
