79 cordoba 360 PLEASE HELP

79cordoba · Aug 17, 2014

I just inherited my grandfathers 1979 chrysler cordoba. Their is a long story and many details which I may accidentally leave out so feel free to ask questions! There is a lot of work to be done but the problem right now is the 360 magnum is starting and will run for 10 seconds off of starting fluid but won't without it. There is no fuel getting to the carter 4 barrel. I would just install a new fuel pump but the lean burn system that used to be on their is troubling me. There is 2 fuel lines coming from the fuel tank, and one return line? One of the fuel lines coming from the tank was cut. The last time the car was shut down it ran. 12 years ago.

No return line. Vent line that should run to the vapor canister. Not sure about the 2 fuel lines. Some pictures may help. Not sure why the lean burn is preventing you from replacing the fuel pump. You should do yourself a favor and remove it anyway

Hi there 79cordoba...

First of all, welcome to the forum. There are a few others with cars similar to yours so you won't be alone. Take a look at the topics posted in the 75-79 section, you might find something helpful. When you say no fuel getting to the carb, have you disconnected lines to see where the fuel stops? I'd check the fuel line going to the carb in case the needle and seat have stuck shut after sitting so long. If no fuel there, I'd see if any gas is available in the line going into the fuel pump. You could blow through that line so make sure there isn't a restriction between the pump and tank. After 12 years, the gas could have gunked up the fuel inlet in the tank and should be drained anyway.

Good luck, let us know how it goes.

Thank you guys so much for the fast responses! First off in reply to hemi rebel I want to fully remove the lean burn system but I'm not sure what is what. I am familiar with every part under a 69 charger 440 but I'm new to all these vaccum hoses! I will try to post pics ASAP but I don't know what parts are lean burn and what are not. And to photon440 I did I troubleshoot the fuel and I'm getting fuel up to right before the pump. Also the lines to the vapor canister are all cut as well.. Ugh grandpa! Haha I will try to keep you guys updated! Thanks so much for the help!

Heres a picture of what I believe is part of the lean burn and is unnecessary but don't want to remove Incase it isnt IMG_8686.jpeg

Before I had to run the motor I would clean everything... if yes been sitting for 12 years there most likely gunk in everything.... go through the whole car.... every gasket.... every fluid after pressure washing the car.... then you will have a good reliable runner... a museum piece left to sit would need a flush and clean also...

Sorry, I don't see your picture. It's easy to post on here, see that bar of icons that shows up when you're posting or replying?

It's the third from the right. Just click on it and it will lead you to whatever folder on your computer you have your picture stored.

sleepar · Aug 17, 2014

I 'll give an example.... say you rebuild the carb.... comes out nice... car runs for 10 minutes the dies.... then you clean the tank and the carb again car runs and dies in30 minutes.... you rebuild the electrical... 60 minutes later the the rear end locks up because the 90 w is like coal tar... then the brakes go out...... you can do a lot of damage to parts useing 12 year old fluids.... Or go through the whole car and everything will be up to PAR... and if something fails you already know something about it and it's not as overwhelming....

Easy as headers.... LOL

That's the part I think is for the lean burn

Heres the vapor canister.. Also for the lean burn?

Hemi Rebel · Aug 17, 2014

The circled part it the cruise control servo. Vapor canister is for hydrocarbon emissions. Nothing to do with lean burn

79cordoba · Aug 17, 2014

So can I remove the vapor canister?

Hemi Rebel · Aug 17, 2014

Lean burn is the ignition system. The computer mounts on the air cleaner and the distributor is specific to the system. The mopar electronic conversion kit has instructions for replacing leanburn and would probably be the most practical way to go about it in this instance.

79cordoba · Aug 17, 2014

And can I remove the cruise control mechanism if I want to? Help clean up the engine bay?

I'm 99% sure all the lean burn is all disconnected

HawkRod · Aug 17, 2014

The part you circled in red may be for the lean burn, I am not familiar with it.

The vapor canister is not for lean burn. There are three connections on it. If I am not mistaken, one goes to a vacuum source, another goes to the carb and the third goes to the return line to the tank. If you clean up the canister they should be marked. Regardless, this helped avoid gas fumes going into the atmosphere, but it was not the lean burn system.

As others have said, you really should clean out the tank after it has sat for 12 years. To start out with, you may want to replace the fuel pump and have it draw fuel from a small plastic bottle in the engine compartment - not to drive it that way, but to get it running. Once it is running OK, then you should go and clean out the old fuel.

My car sat for around 17 years. I tried double filters and other tricks, only to gunk up the carb MULTIPLE times before I finally gave up and did what I should have done in the first place...

Good luck with your project (and welcome too)!

You can disconnect it but you will see that the speedometer cable goes through it. You will need a different cable.

I drained the fuel tank and put in stabil and 10 gallons of new gas

Understood. But my tank was full of what seemed like fine silt. Draining the tank did nothing, as the 'silt' was still there. Do yourself favor and check it, or you can be fighting crap in the fuel.

I got stuck in the middle of a narrow 2 lane road with no shoulder when my engine stalled due to crap in the gas finally killing my fuel filters and carb. It was no fun....

I'm in a similar situation as 79cordoba. I'm buying a 1976 that was last on the road in 2006 or so. I'll be ordering a digital FSM soon, but how do you empty a gas tank, and how do you dispose of the old, bad stuff. Thanks, Newp

slepr1 · Aug 19, 2014

I recently took my 77 Cordoba out of a 10 year hibernation. I easily drained the old fuel by disconnecting the rubber fuel line from where it connects to the metal fuel line by the gas tank, stuck the rubber end into a larger tight fitting hose and the gas siphoned out automatically. It was easy to access and simple to do. Another way is to disconnect the fuel line attachment that goes to your fuel pump and hook up an electric pump to it. Make sure to change the fuel filter and prepare to have the carb rebuilt. Before firing it up we dumped WD30 in each cylinder through the spark plug holes and let it sit overnight. After it fired up we changed the oil soon after.

Fox Lake, Illinois!

I grew up in Fox Lake! I live in texas now, but spent plenty of years racing up and down Rt 12 and sneaking the back roads to Wilmot. Dog and Suds in Ingleside was the best cruise spot. Welcome and let me know what a fellow Fox Laker can do to help.

BTW... if the car sat for 12 years, I'd start by cleaning and replacing the fuel system. The fact that the car will run with starting fluid leads me to belive that the ignition is working? I have brought several old cars back to life but it required a new fuel pump/filter, blowing clear the fuel lines, a check of the gas tank. My carbs have all (surprising) been ok---new gas made a difference.

79cordoba · Aug 23, 2014

No way! We live a golf shot from dog n suds ! Me and my father take the charger up every saterday
