1978 Jeep CJ5 V8 Four Wheel Drive Manual

In attempting to get a vehicle running again that had sat for approximately 2 years, after replacing the battery and the fuel, the only way to start it was to pour gas down the carb and it would cut off immediately after it ran through that gas. Figuring it was a fuel delivery I checked the fuel lines and replaced the fuel pump (mechanical). Still wouldn't start and cut off after pouring gas down the carb. Rebuild and cleaned carb, still wouldn't start cold (unless vehicle had been running withing the past hour or so). Dealt with the starting issue by pouring gas down the carb whenever I had a cold start. Now the vehicle won't start even attempting a rolling start. Is this an ignition problem (starter, battery, starter solenoid good), haven't replaced the plugs or wires?

Hi
Does starter operate? Is there spark at plugs? Does choke close on carb when cold? Plugs good idea to put in new ones.
Let me know

Starter is in good operation. Planning on replacing the plugs and recharging the battery tonight. If the plugs were bad, wouldn't I have a problem with vehicle running operation? I have only had a problem during cold starting to this point.

See my profile, and many other CJ 5 and CJ 7s I have answered.

I do not mean to butt in, but it sorta sounds like a Choke, maybe vacuum line issue.

Are you getting spark at the plugs during "The Cold Start Issue?"

Does it spit and sputter--but no cranky, when cold.

Just trying to distinguish fuel issue from spark issue.

Thanks everyone, turned out to be a myriad of things. I adjusted the choke to get it seated properly while not operational. Next, I found a crack in a metallic vacuum line lead and sealed that with JB weld. Pulled all the plugs and they were all wet fouled from pouring gas down the carberator to start, replaced them, recharged the battery and it fired right up. Appreciate all the input.
