hello everyone

I have a question that I am hoping someone can point me in the right direction. I have a CJ2A that I inherited from my dad that has always started just fine. Recently it just won’t fire up. It turns over great but just won’t fire. I have replaced the spark plugs and wires by still no luck. I’m not really sure where else to start. Sorry I’m new to this. Any help would be appreciated. 
Thanks 
Cory

Lots of things about this posted. Condenser being the most mentioned. A lot of things to check like clean connections in the wiring. Nice looking dog but I am partial to Labs and Border Collies.

As stated, condenser is common. It’s also been very damp in our area. I have had issues with moisture in the distributor cap in damp weather. Normally in warmer weather though. 

To be honest it could be a lot of things. I would check for a good hot spark at the points. You can pull the cap off and watch the points with a helper turning it over or open and close the points with a screwdriver with the key on to check. Weak or no spark here will point you in one direction and good spark will lead you in the other direction. 

Would be best to post this in the tech help area to get more feedback.

Besides the obvious Sling Blade quote of "It aint got no gas in it," you can also pull the intake off the carb, open the choke butterfly and look down the carb throat while pushing the throttle open to see if the accelerator pump is spraying fuel. I like to use a spark plug checker to check for spark. Much handier than the screwdriver in the spark plug boot method. While you can see the top of the carb, you can also make sure the choke is closing when you pull the choke knob. No choky, No starty. Let us know what you find!

Safety Sally says don't do this but pour a little petrol down the carb.  If it fires or sounds like it wants to, spark is probably still ok, chase the fuel/carb issue, if not chase the spark issue.
How long has time pass since "recently"?  If used and it sits around, ethanol gas is horrible.

Safety Sally doesn't come around my house.  I do that all the time.  Is that why she never visits any more?  LOL

Nothing personal here but, do you really know how to start an old jeep, or any other old vehicle? Have you started it before, or only watched your Dad start it? What procedure are you using? Are you using the choke? Are you giving the gas pedal a pump or two? Are you cranking on it long enough to give it a chance to start?
  The reason I ask, we had a young fellow a few years back who could not get his jeep to start. The thread went on for several pages. Turns out, he thought that he should just push-and-release the button and it should start right up, just like his Nissan, or Honda, or whatever. It don't work that way.   BW
Happy Trails! Good-bye, Good Luck, and May the Good Lord Take a Likin' to You!

I had to laugh but Sally Safety won't come back because the last time you did the gas down the carb bit you blew her into the next county. I have started many vehicles that way.

I have started it many many times. Usually takes a choke and a couple pumps of the gas pedal and 10-15 seconds of turning over and then would fire up! 
I’ve been traveling for work a lot past couple weeks and when I get some time I’m going spend some time and go through everything.

Yep,
   First thing I would try is to pour a cap-full of petrol down the carb with throttle closed and crank her over to see if she'll Pop !

   If not, carefully clean the points contacts with emery cloth and then clean paper pulling through very gently. Clean white 20-lb bond paper, and holding open slightly with a screwdriver so not to tear the bond paper.
or use a cotton swab wit acetone holding points open til dry.

   The old distributors all have a vent hole to air, and humid moist air will corrode the point contacts. I must clean most all points-ignition contacts if a vehicle has sat for 2 or more years.

    Could be the pump may not be picking up the fuel yet.

You need three things to start and run, fuel, spark and compression. Do a little diagnosing before replacing parts. Using a spark tester check for spark at the plug end of the wire. No spark, diagnose the ignition system. Remove the air cleaner and check for fuel when pumping the accelerator. No fuel, diagnose the fuel system. If both of those check out, remove the plugs and run a compression check. No, or weak compression, diagnose that issue. If you have compression, fuel and ignition you need to confirm that the ignition and compression are happening at the correct time. Go through setting the timing flow charts to confirm all is correct. Good luck
