no spark one cylinder. on 1994 Toyota Pickup

Connections are all clean and greased, spark plug wires have been replaced, but I'm not getting a spark from the distributor cap on the number 5 cylinder, Any ideas how to fix that? Thanks.

Seen the shim adjusted valves on these engine "hold" their clearance for 100,00 miles but important (yet neglected) service after that. Valve gets tight and then burns or causes a misfire/ possible emission test failure particularly at idle (high hydrocarbons).

Sounds like you distributor cap has failed about $12 to $26 at any auto parts store don't forget to change the rotor also.
found the problem, I replaced distributor cap and rotor since it looked bad, still same problem, after doing a compression test found out it's a exhaust valve, at 280 000 miles it's time swap the engine. to the auto wrecker I go
