I changed the spark plugs and wires on my chevy s10 2wd pick up, which is a 4 cylinder and now it will not turn over. I might have the wires mixed up on the distributer cap. Can someone show me a picture as to the correct positioning. I know that the firing order is 1-3-4-2 but how do I know which is which on the distributor cap?

GET A PIECE PAPER DRAW A LARGE CIRCLE TOP UPPER HALF CIRCLE LEFT TO RIGHT WRITE NUMBERS 1 AND 3 BOTTOM HALF CIRCLE LEFT TO RIGHT RIGHT NUMBERS 2 AND 4 THAT YOUR DISTRIBUTOR SPARK PLUGS WIRES LOCATION.STANDING ON SIDE OF ENGINE WHERE DISTRIBUTOR IS LOOKING DOWN AT DISTRIBUTOR 1 AND 3 FIRST TWO SPARK PLUGS TERMINALS NEXT TO ENGINE. AND 2 AND 4 SPARK PLUGS TERMINAL ON CAP FACING YOU. THIS IS CYLINDERS LOCATIONS STANDING IN FRONT OF ENGINE.RUN WIRES FROM DISTRIBUTOR CAP TO PLUGS TO THE ENGINE SPARK PLUGS.

The S-10 came with 3 difference 4 cylinder engines. Each one has a different location for the number 1 spark plug wire in the distributor. You did not say which engine your's has. So the easiest way to set up the distributor is to turn the engine by hand until you see the timing marks line up on the crank pulley. Set your rotor button on the dist. shaft, and line the tip up with one of the wire connections in the cap. That will be number 1 location in the cap. The 2.0L and the 2.5L 4 cyl. dist. turns clockwise when standing at the grill, so it will go from the rotor point number 1-3-4-2. The 1.9L 4 cyl. dist. turns counterclockwise and you just rewire in the opposite way. I hope this is clear as mud and makes all your hard work easy.

I believe it is the same as my 98 s10 2.2 l and the firing order is 1-4-2-3 (where cylinder #1 is the closest to the fire wall) and your distributor has the plug wires running almost vertically 1st cylinder = the very bottom and 4th cylinder = second from the bottom and 2nd cylinder = second from the top and 3rd cylinder = the top connection on the distributor.
