You need to set the engine back to TDC. TDC is 'top dead center', this means that the engine's #1 piston is at the peak of its compression rotation. There should be a little notch mark on the engine block near the crankcase (a hayne's manual for you car would explain all this). Anyways once you have set the engine to TDC, you can then put the distibutor back in, making sure it is in the correct position for firing. Also be sure to check spark plugs and wires for weak linkage. Don't forget that all 4-stroke engines require that the timing mark be at TDC WHEN #1 CYLINDER IS AT TOP OF COMPRESSION STROKE! Very common mistake as the TDC mark will show twice for every revolution of the Distributor. what second answer said is thrue but it dosent really mater which cycle you pick as long you are at TDC.
and to elaborate a little more about this tread. it is almost impossible for any one to incorrectly line up the distributor back into the engine be cause they usually have a guide at the bottom of the shaft. unless you miss a line the shaft 180 degrees.
If that was the case all you have to do is pick cylinder 1 firing order to be distributor cap #3 wire out put and go with the order from there
same order 1-3-4-2
