#2 cylinder not firing

Nov 26, 2009 7 Replies

boy, am I perplexed. seems there's miss. I pulled spark plug wires out of the dist. cap , one at a time at idle. of course each wire pulled produced a noticeable bigger miss until I got to #2. I replaced the distributor cap , the plug, wire and checked the compression. WTF could it be?


Did you remove the valve cover and confirm that both valves open and close normally on #2?

Compression really *is* good?

Possible vacuum leak, at manifold-to-head gasket for one.

well, I did check the compression , it's 150 in #2. and I did check the lash on all cylinders. The weird part is I located the miss by looking for the spark to jump into the cap on each cylinder and #2 had no spark jump when I held the wire close to the socket. all other cylinders had the spark jump just fine. thanks for the suggestions.

"and #2 had no spark jump" Ah.

That is a horse of a different color.

Curious. And you replaced the cap and the wire(s).

Is it remotely possible that the Coil is not producing any spark when the distrib cam lobe for #2 gets in position to open the points?

If this is a vac distrib, also have a look at the tiny braided pigtail connected to the advance plate. If broken, that can interrupt spark (though why only #2 is a mystery).;

I have once seen a dead cylinder spark with an electronic ignition kit installed in the distributor!

So I will ask if you have points or is the distributor now equipped with electronic ign?

I usually sand the area where the condenser grounds to make sure that does not cause problems. I have seen a tachometer cause problems too!

I will assume that you do not have fuel injection on this engine!

AND why d>> In article

Well, Mystery solved! after replacing just about all of the above, I thought why just one cylinder not getting the juice. why , the distributor wasn't doing it's job. So, I grabbed one off an engine that was running fine. and Voila! so, I just assumed, even tho. the cam in the old 009 "looked" OK, it must be worn down on #2. I may even extract the "shaft" to measure it. No, it doesn't seem to wobble. thanks , again for your suggestions. Boy, when these cars get old , they sure try some "interesting'" tricks. Who's the turkey? g.

strange but thanks for providing us with the solution to the problem! ;-)
