Answer
Your firing order is 1.5.3.6.2.4

But you need to know which hole to use for #1 - unless you remember or can tell by looking carefully at how the old plug wires are bent.

To find out, manually turn the engine by pulling on the fan belt or by putting a wrench on the big bolt at the front of the crankshaft - turn it to where the timing pointer is pointing at "TDC" on the pulley.  Now, your engine is stopped at the firing point for either #1 or #6 (you can't tell which because on a 4 stroke engine, the crank goes around twice for each rotation of the distributor rotor).  

You can take a 50-50 chance and start putting the plug wires in with #1 going to the wire socket that the rotor is stopped at, and adding the other wires in firing order around the cap in the same direction as the rotor turns when you crank the engine.  The engine will now start and run properly, or not start at all.

If the car won't run that way, you can swap the wires in the cap to correct the error - put #1 in the old #6 hole, #5 in the old #2 hole, etc. - until you have moved all 6 wires directly across the cap - now it should run.

If this is too confusing, take #1's spark plug out of the hole and put your finger in the hole while someone cranks the engine in short spurts - when you feel pressure in #1 hole, you know you are coming up on #1's firing position - the rotor will be pointing at #1 spark plug wire socket, or very close to it, and nowhere near #6, which is on the other side of the cap.
