do a spark test
Get an insulated screw driver and stick it in the plug wire and hold the screwdriver about 1/4 in. away from the block, or any unpainted surface, and crank the engine. Normal spark should occur. make sure you don't hold the wire while doing this, use spark plug wire pullers that are insulated or hold the insulated part of the screwdriver. also make sure you don't do this test around fuel injectors or anywhere where fuel might be present.
