bad fuse,bad coils, bad ignition modual
If you don't have spark at the plugs, or at the distributor cap, the problem is probably a faulty ignition module. This is located under the distributor cap and ignition rotor. You need test equipment to check the coils, modules and pole pieces.
If you mean the starter will not turn over the engine, check the battery. vbd
Double check the ground, and make sure the cap on the Optispark unit isn't what's arcing instead.
check for spark
Few things. Check first of all the spark plugs make sure they don't need to be changed. Then it if they are in good condition that is not burnt or covered in oil/grease (if so that might be the problem change them) check the spark plug wires and make sure the spark gets to the end. But if the spark does show but it still doesn't ignite its most likely the timing. If no spark go to the rotor and make sure that's its in a good condition. Most likely its the sparkplugs or the wires less likely the distributor. Check them in any order you preffer. But my guess it would be the spark plugs

should be .035
No spark would usually be the ignition coil.
To add, this is a 5.7 v8 engine.
45 ths.
V8
on the left side of the motor by the spark plugs
I'm guessing you mean spark plug gap? .050
You can probably only get to 2 or 3 plugs from the top, but the rest you have to get from underneath the vehicle.
the Ignition coil has most likely shorted out
