The firing order is 1-2-4-5-3. Cylinder 1 should be lined up with the mark that is cut into the rim of the distributor (where the rotor should be pointing when the engine is at TDC). The firing order is cast into the cylinder head just above the cylinder 2-4 spark plugs IIRC. On the engine, this may seem obvious but just in case, the cylinder are numbered 1-5 starting at the front of the car going rearward.

I tried assembling it like the old one and it continues to hesitate and to back fire horribly.  Which is why I changed the plug wires in the first place.  The timing is still all off.
