Getting 84 CJ-7 4Cyl started again??

ok, I have an 84 Cj-7 with the 4 cylinder in it.. I currently live in Alabama but the jeep is located at my parents' house in Texas.. it is sitting in their barn and hasnt been started in over a year.. probably closer to several years.

I will be there for a full Week and was wanting to work on it and get it running again.

I need to drain the gas since it is bad..

what are the basic steps that I need to take to try to get this thing going again?

any tips and tricks are much appreciated.

like I said, I have 7 days.. it isn't life or death to get this thing going.. just wanted to try to get it going again.

thanks for your help.

1. New battery, fuel filters before/after fuel pump, temporary hose from a gas can to the pump. Put a little gas in the carb and see if it will start/run on its own. Might need to keep feeding it a little gas down the carb before it starts pumping fuel and on its own. If that never happens, replace the fuel pump and try again.

2. If #1 works, try the fuel in the tank. It should not be bad after only a couple of years unless it was bad to start with. I've used older.

3. If #2 is good, try to take it for a ride and see if it bogs down, etc. If it does I would start w/ a carb rebuild. The carb may not need it though so I wouldn't just jump in and do it without seeing how its behaving first.

If it were me I would pull the distributor an run the oil pump with a drill to get oil up in the motor first, then pull all the plugs and crank the motor over several times before trying to get it to fire. Any motor that has not been ran for a year or more I start by doing this before trying to start it. You can spin a dry rod or main bearing very easy. Also put some tranny fluid in the plug holes before cranking the motor, this will lubricate the rings.
My 2 cents
Good luck

This seems to be a popular way to go: pull out the spark plugs, put a small amount of lubricating oil in each cylinder, let it soak in, and then try to turn the engine by hand using a wrench on the main pulley. If the engine turns OK by hand, then crank it with the starter.

The single barrel carburetor on my 83' had to be rebuilt recently. I forget exactly the details on what the rebuilder explained the functionality of the accelerator pump was but it is a little more integral to how the carb works than on other carbs. Something to keep in mind if it is not running well.

I am curious to see who all still keeps the original 4 squirrels in their rigs. I have the f134 in the willys but how many actually stick with the iron duke or the amc and have no complaints.

ok, late update... I pulled the spark plugs and poured a small amount of marvel mystery oil in each cylinder and let sit for a day... the engine would turn by hand...

we hooked a bottle of gas to the carb and plugged in a new battery... started right up and ran great... crazy that it worked like that... I guarantee that if my '12 JK unlimited were to sit for 5 years, it would not start right up...

Thanks for posting the update! Glad you got it running. Sometimes the simplicity of older technology has some benefits.

That's the exact same thing I did with mine after it sat for eleven years. Started up and ran semi-good.
Then all of the gaskets and seals fell apart on about a daily basis....

Glad you got it fired up.

Yeah I just ordered a new ignition switch and a clutch master cylinder. Hopefully I will be able to install them this weekend.

Ok. I just installed the new ignition switch and have a problem/question. When I turn the switch forward as if it were starting the jeep, there is no spring back to the run position. Does that make sense?

I haven't looked at the wiring my dad did when he put in the button starter.

It is an 84 '7 with a 4cyl and non tilt wheel.

Thanks a lot.

Ditto, 10cc of thin oil and let it set for a few hours while you tinker with other parts.

it not that I do not have any complaints, its just that I do not want to spend the money on an old piece of rusty jeep to install a bigger engine.

the little amc 4 banger pulls the my old 1984 cj jeep way faster than the frontend can hold the road, if there are any dips or potholes.

It just an old jeep, but its my jeep and we have been together for a long time.
do not know how old you are, but when you are older like me, you just hang on to old friends: good, bad or indifferent.

nothing finer: on a beautiful spring day, just loafing along on a back road, riding in my old jeep listening to some tunes, maybe having a friend or grandkid to ride along with me.

do not really need a big engine for that.

have a good day,
