Ashton, I just had two more thoughts... When you replaced the Disty, some rotors will go on in three different diections. The factory ones will not, they will only go on in one dirrection, but some after markets will. You may have put the rotor on facing the wrong dirrection essentially missaligning the spark by about 33 degrees.
If that checks out, and so does the timming belt, then the next thing to check would be fuel. You can jump the FP and the GND pins in the diagnostic box under the hood with the key on, and the fuel pump should run. Easy way to check to see if the FP is working. Also, there is a 17mm nut on the exit side of the fuel rail (by disty), you can loosen this nut (with the FP off) and see if fuel squirts out. it has two brass washers, so you can just tighten it back up with no adverse effects.
Josh, i'll give you a call on Saturday around noon to tell you if I'll be done with the bathroom in time to help you.
