Remove a spark plug from the engine and put the plug wire back on the plug. Then position the spark plug such that the lower part of the spark plug is touching the block, with no gap.
Then crank the motor and watch for a spark in the gap of the spark plug. Chances are if you have a spark in one cylinder, you will have spark in all of them. But it wouldn't hurt to check all cylinders.
This works best in a garage, or in the shade, so you can see the spark. You can often hear the spark too.
If you see a spark, then you probably have a fuel issue.
