My 58 ford keeps stalling. I have a fresh engine, rebuilt carburetor, new fuel pump and fuel filter, rebuilt generator, new coil, blew out fuel lines and flushed and dipped fuel tank, rechecked spark plugs, and vacuum lines and all is ok. it dosen't happen right away, usually around 15 mins of driving. I have a new air filter and I checked vent tube on fuel tank and it wasn't clogged. It's not consistant when it happens either. sometimes it bogs down like it wants to die but kicks back on and I can drive another 5 mins or so. Sometimes it bogs down and just dies. I don't know what else to do. What do you guys think?

Does it happen while cruising, idling, both?

Fuel pump sucking air somewhere along the inlet line?  Coil breaking down?  Condenser going bad?  Loose choke that’s flopping closed?  When it dies, check to see if the carb is out of fuel.  Another thing to do when it dies is to spin the engine over with the key on and the coil wire pulled from the distributor cap and help about ¼“ from a ground and see if you have a nice strong spark.

Is it possible that the gas cap got replaced with a non vented cap?

@ Charlie-It happens while cruising

@Ted- I have a new coil and wires, a new condenser, I checked the choke and it's not loose, the inlet line to the fuel pump is new and tight so I don't think it is sucking in air and I will check the spark next...

@Jeff- I got the cap from the local parts store so I don't know... should it be vented like the oil cap is?

@Jeff- The tank is vented and I checked that... but the cap is not. Do I need a vented cap and a vented tank?
By PF Arcand - 14 Years Ago
No, you dont need a vented cap as long as the vent tube is clear. Having both would just increase evaporation. However, a couple of times this site has had reports of Mud Dauber Wasps trying to start nests in the vent tube. Make sure it's clear...

I checked vent tube and it was clear... I drained my tank today and all was ok...what else? I just brought the car back from the dead after 10 years in a field and Im starting to think she would of rather stayed that way lol

Next time it dies, do what Ted said. He's thinking you may have a coil issue. If you have a good spark pulll the air cleaner and pump the carb to see if there's fuel in the carb. Let's determine what the cause is by the process of elimination.

It could be the ignition. Coil, condenser or what happened to me once. I had a 1971 Capri that would randomly stall and I was convinced it was a problem with the carb. It turned out to be a bad contact on the wire inside of the distributor that grounded the points. That had me going for a long time.

My point is that it could be a lot of things other than a fuel issue.  A problem like you have requires an open mind. Pete

Check the pick up tube in the gas tank,had a tank cleaned and repaired but it was forgotten about and was clogged.  It would run about 25 minutes and then act like it was running out of gas and sometimes make it home,cleaned it out and no more problems.

Hey Monk;;   Don't remember the year that ford started with a  resistor wire in the loom going to the engine compartment, but if you do not have a resistor on the coil check for this  wire-- believe it was a light gray or could be pink. Somebody here I'm sure will know the year they started.  Hope this helps--  God Bless  Eddie

Thanks guys for all your ideas I will check them all one by one Smile

Add checking the ground strap inside the distributor to the list and also insuring that all electrical connections within the distributor are properly tightened.   Even a loose condenser can be tough one to find unless you're looking for it.

I had the same type thing happen last year when I first bought my 55.  It would drive great for about 15 minutes and then start sputtering.  When I would come to a stop it would cough and sputter then die like it was out of gas or vapor locked.  I could floor the gas peddle and turn it over for 10 seconds or more and it would fire back up.  I put on a clear gas filter and could see it was starving for gas when it was doing this. 

I ended up changing the tea pot carb for a Holley 390 and dropping the electric fuel pump for an FE pump.  Put in new gas and it ran great after.  I had also dropped the tank and found it was sealed previously. 

The final variable was in draining the gas from the tank (winter blend bought in March) and replacing it with fresh gas in about May (summer blend).  I was told later that it may have been the winter blend in combination with the electric pump causing a void in the fuel delivery to the carb.  I do not know about this for sure, maybe someone else has an opinion on fuel quality.

And the winner is PETE!!!! Thanks for everyone's help. The problem was a bad ignition. Went and got a new one for $40. BigGrin

So what exactly was the problem?Which component failed?Helps others in the future who experience a similar problem.
By Maybelle lee - 14 Years Ago
It was a bad ignition switch causing the car to bog down and feel like it was starving for fuel. I changed that out and kept my cylinder and now Im on to my next problem...Distributer is grinding when I give it gas.
