If you're replacing the spark plugs in your car engine, you'll need to set the gap before reseating the spark plug. The gap is the distance electricity arcs between the ground electrode and center electrode. The gap must be set correctly to ensure maximum performance. Here's how to set the gap of a spark plug.

1. Remove the spark plug wires. Use a socket wrench to remove the spark plugs from their chambers.
   
2. Clean the spark plug if you are not replacing it with a new one. Remove all dirt and debris from the spark plug.
   
3. Check the owner's manual for your car (or any appliance with spark plugs) to find out the recommended gap setting.
   
4. Use a gap tool to check the gap of the spark plug. Slip the tool between the ground electrode and center electrode. The gap tool should fit snugly at the recommended gap width indicated on the tool.
   
5. Push the tool between the electrodes a few times to ensure proper gap. If the gap is too wide, push the ground electrode firmly against a flat surface to narrow the gap and then check again with the gap tool.
   
6. Repeat Step 5 as necessary until you reach the correct gap. Reseat the spark plug and reattach the spark plug wires
   

Good Luck

CHECK THE IGNITION FUSE OR IGNITION MODULE FUSE AND CHECK ECM FUSE ALSO. TELL ME ARE YOU GETTING FUEL.YOU DID NOT MENTION YEAR AND MODEL.BECAUSE CRANKSHAFT SENSOR WILL CAUSE NO SPARK ALSO.

You have a 1986 454 engine with an old style breaker point ignition distributor, GM has not used a breaker point ignition for their V-8 engines since 1974, is that an older distributor or something after-market?

The ignition points dwell angle for that engine should be set at 29-31 degrees dwell (a dwell meter would be the most accurate way to set the ignition points), or a .019 in. point gap.

The spark plug gap for that engine would be .035 in. and the timing should be set at 10 degrees before top dead center.
