1984 Jeep CJ7 Stalling

I have owned my Jeep since 1990. It has always had a stalling problem. Since then I have had almost the entire jeep rebuilt/replaced. The last time I drove it (it has been sitting for a couple of years now) was after a major re-hual and the stalling problem slowly started coming back and got worse and worse. During that time I noticed that I would fill the gas tank and the car would run fine for a period, then start stalling (during idle/always had to keep it revved up) until it simply would not start. I would then put gas into it and it would run again. I would usually run down to about a half a tank and then not start - this occurred for awhile - seemed to get worse, then finally it would not start at all even with new gas. I have not done really any work on the car myself - but want to start. After researching a little I thought it may be a fuel problem (i.E. Filter, lines or tank) The fuel tank is one of the few original parts of the Jeep. I would like any ideas or even advice on how to test my theory before digging into trying to take off, drain and clean the tank. Thanks.

See my profile, I answer many of the CJ problems.

I am really experienced with them, My primary drivers since 1981

Owned 6 CJs and 1 Willys

Presently have 1977 CJ 5 and Willys.

I will help you thru this all the way---testing and all!

See "1985 CJ 7 Stalls When Hot" several down below yours in forum (14 responses)

I'm not sending you there for a fix--but to get you familiar with some things that yours may lack. And to get familiar with my style of help.

Some items in that post may PERTAIN to you also---look at fuel filter setup. Yours the same?

You will see the extent I will help you! I CAN SEND PICS (let me know if necessary)

Are you (or buddies) able to perform relatively EZ fuel tests. Minor Auto tools available?

Such as removing certain lines in the engine compartment and testing for flow, volume at certain number of seconds in a measured container?

Or a shot of starter fluid in the Carb to see if it TRIES to start (lack of fuel issue)?

I need to know your capabilities on your end.

Medic,

Thanks so much for your response - I apologize for the delay getting back to you, I was travelling and did not have access to the Net. With regard to your questions, I do not really know how to do any of the stuff that you mention - other than shooting some starter fluid in the carb. I will do this immediately to see what happens. I did it prior to putting the car in storage and it would start up and then stop immediately indicating ( I assume) that it was getting no fuel at all. I do not have many tools but am certainly willing to obtain them since I would like to begin working on the Jeep from now on as a hobby.

I will als check out your other posts (I am figuring out how to navigate the site).

Thanks again and I will get back to you as soon as I check the starter fluid idea.

Rog, I check my posts frequently, I can guide you thru this. Put your mind at ease, Please get you a Chilton or Haynes Manual. Keep it in your rig for roadside stuff.I can help you reference it for these fixes and tests WE are going to do.

Your Model (CJ 5 and CJ 7) maybe Years '71-'90 ( the covers change over the years) But content is the same. About $30 at major Parts Stores

That how I started out!

Want Your test results. Detailed, it did this when I did that etc etc

Tools you have?

Any experienced HELP on your end?

PS: thanks for the reply, I get few. This is just my hobby. Especially the CJ stuff!
