The easiest way to check for spark is to use the diagnostic tool CheckSpark. You simply clip it on the wire, or move it from wire to wire on a multi cylinder engine, and read the lights, Red means no spark, flashing red means low spark, shorted plug ,or flooded condition, Yellow light means high spark ,indicating a bad plug or wire, and a green light means ,all is good with this plug and wire look elsewhere for your problem. CheckSpark is like having a oscilloscope in your hand. You can get them on e-bay Only $24.95 ,and it works on all engines with plugs and wires.

You need to check wires. Make sure that you connected plug wires in the correct order. Check that wires are sitting tightly on spark plugs. If it didn't work, remove spark plugs and check the gap for all of them. Install the spark plugs and try to start again. If it didn't work install old spark plugs and try again. If it didn't work check the fuse box under the hood. Hopefully it works.
