No 2 cylinder not firing

[Unimatrix1066]

Just going through jobs to do on my car one cylinder is not firing there is a spark , and there is compression as I ve checked this also no choke is required from cold?

Is it definitely only one cylinder not firing? Are the leads in the correct order? Try changing the plug in case it doesn't fire when under pressure. How have you confirmed that it is No. 2 not firing? What are the compression readings for all cylinders?

As above, but also- hold the plug cap 1/8" away from the plug top (insulated pliers...) - does it pick up and start firing now? Also worth checking the valve gaps before testing the compressions.

I removed other leads and it engine stops , I checked the compression by turning over the engine and seeing if there pressure from the plug hole. It seemed equal to other cylinders
To check the non firing cylinder while the engine was running it removed each lead and only one did not alter the running of the engine

Good basic tests, but may not show some problems. As a next step, try swapping the plugs between 1 & 2 - does the fault stay with 2, or move to 1?

Did you hold the plug cap 1/8" away ??????????

I just took each cap off so it was nowhere near the spark plug anode, plus a spark was present on plug when earthed to the block

If you can see a weak spark on the plug, then as suggested before, swap two plugs over and see if the fault moves. If yes, then it's a failed plug, if no, then it's a lead or cap problem (or compression as the test used is not perfect). Can you try the tests suggested by Roy and me, and then report back. Not needing choke suggests a rich mixture, but let's deal with one thing at a time.

If you don't try the suggested tests, WE CAN'T HELP YOU....

I have not looked at it since yesterday so will try the tests suggest , I will not be until the weekend now
