Blowing fuse(18-20A)

Hello. I'm in the final stages of replacing my head gaskets. I replaced all gaskets and now im all put together but i keep blowing fuse 18, 20a.
Replaced coil and wires, now im on my way to the junk yard to find a new ignition module cause i steped on it. seems to work but its cracked now so il lreplace that. everythng works until i plug in the coil. Please help

Figured everything out!
Thats right along the lines of what I was thinking, so I did some back tracking to find my problem and I found that the coil and the crank shaft sensor plugs were swopped. My help was just plugging wires in where they fit, so i swopped them back and she ran perfectly. Thanks for the tip.
