1988 SUZUKI Samurai: 3rd cylinder not firing, Any ideas?

I'm currently working on a 1988 SUZUKI Samurai, And i've tried numerous things to try to get the 3rd cylinder to fire, with no luck as of yet.. Its a 4 cylinder and the distributor is fine, Used fuel cleaners, replaced the fuel pump, fuel filter, etc.. Any ideas on what I could try?1988 SUZUKI Samurai: 3rd cylinder not firing, Any ideas?
Connect the spark plug wire for the cylinder that is firing to other cylinders, one at a time



If they do fire respectively, the problem is with the spark delivery to the three faulty ones (the mechanicals are in order)



Check if the firing order has been mixed up



Check if the spark delivery had leaked due to poor conncection/insulation, or faulty ignition coil1988 SUZUKI Samurai: 3rd cylinder not firing, Any ideas?
Bad gas (not using Shell, Texaco, or Chevron) (and use regular, not super) will cause gunk to build up on the valves, even up high enough to prevent them from actually closing all the way.



You diidnt mention compression check, and you didnt mention if you were getting spark or not.1988 SUZUKI Samurai: 3rd cylinder not firing, Any ideas?
You could have stretched and broken the metal wire within the spark plug wire.

Also, you could have a short circuit within the spark plug boot due to anti seize compound getting smeared there by accident.



I'd also change the plugs and double check the gaps on every one,
