Sounds like you are jumping arund a bit there from one symptom to another without being methodical and ruling something out.


Ok, you now know the fuel pump works

But you are not getting fuel into the engine.

That only leaves the carb. You are going to have verify this is the problem and take it apart. A common issue is the float bowl and the inlet valve. A piece of dirt can lodge in the inlet or the float be set too low.

Those platinum plugs may not be good. Ordinary plugs work best, nothing fancy. You need to gap them correctly and check you have a regular bright crisp blue spark. If tey are gapped and you do not it is because your coil is not deenergising properly. Have a look at the voltage at the coil and whether the engine is properly grounded.

Thank you all for your help. I am very new this and have enjoyed working on the jeep. As for the spark plugs they are gapped correctly but did not have a blue spark. I am not sure how to start on either one of the recommendation you had for the carb or volt check. Do you know of a good step by step explanation out there?

The float bowl was the problem. I have got the engine running again. However, when the engine is cold I have to spray carb cleaner in the carb to start the engine. After it warms up I do not have any problems. Do you all have any recommendation?
