39 Trouble shooting!

[Yngve]

I am having problems with my 39 std Coupe. When it gets warm it stops, sounds just like when you run out of gas.

This is what I have tried:

- Put in a new original Coil and Condensator
-New sparkplugs and wires
-New fuel pump and lines
-Opened the carb and cleaned the jets, carb is freshly rebuilt.

I have no idea what is wrong, when i get the car back home it runs like it should. At first i thought it was a overheated coil, but now i do not know.

Any ideas?

Coil. Have Skip Haney in Florida rebuilt it. Charles

Yes, I also thought about the coil, and put in a new one. Same problem.

You may want to try another condensor; many of them are junk. Recommend NAPA IH-200 (I think that's the correct #). Good luck. Steve

Bought the new condensator at macs, I will try the old one again. Thanks.

It's always a good idea to replace and / or repair ONE piece at a time when trouble shooting.
Replacing the coil and condenser were great places to start your search for the culprit part(s). However, never, never, (did I say "never"?) assume a replacement part is good.
I would be willing to bet perhaps half the folks that repair their own vehicles would agree with that advice.

I purchased one from MACs several years ago and the same thing happened with my 46-at night on a dark road. If you live close to a NAPA, I would try them.

Especially with condensors!

He He, yes it happends on a dark road in the middle of now where. And to day it is rain and thunder....

I live in Norway, so NAPA is far away...

How hot does it get in Norway in the summer...? It could be a simple case of "Vapor Lock"...

I agree. And sometimes you get completely lost. Going out for a test ride now with the old condensator.

Had a condenser go bad on a new Mallory Dist. on my 8BA. Took me 2 days to find it. Put a used one from my 67 mustang 6cyl. worked great. Still on the car 6yrs and 2500 miles later.

Could be debris in the gas tank that floats around until it plugs up the pickup tube. Shut off the engine and the debris floats away from the pickup tube eventually and the engine restarts. Also check to see if the gas cap is vented.

Tried another condenser, same problem. The fuel tank is clean, and looks new. Even opened the new fuel pump, to see if there was any dirt in it. It was cleen.

I will take the dizzy out to morrow and change the points and give it a tune up, this was done by a shop in the US before i bought the car. I can see the parts inside looks new, when i take of the coil. But you never now.

Thanks for the tips guys, hope we can solve the problem.

Go for a new style ( non-original ) 6 volt coil and an adaptor kit for the top of the distributor.

There were several response that should not be ignored. Especially since you said it "seems like I run out of gas". 1. How hot is it in Norway when this is happening ? and 2. could it be vapor lock ? Do you have ethanol (alcohol) in your gas ? Do you have an electric fuel pump pushing through your mechanical pump. That will help the barners put the finger on the issue.

[OLD...BILL]

Any ideas ?? YES,.. can you say Ignition Switch .. is it hot, or warm, when this shut down happens ?? It should not be even warm, bad or poor contacts, will give you exactly what your experiening ... a quick check with your volt meter, it should read a full 6 volts, and the connections should be tight, ( snug ) .... and I do agree "One part at a time", when testing ?? and if you fix it with a new part, try the old part again, you may have just made a new or better contact, somewhere, it worth knowing .... OLD....BILL

Any chance that your gas cap or tank is not vented.

I agree with Kube... Never assume new parts are always good... especially NORS condensers, coils, etc. I use a early ford Heyer test set, what the dealers used back then to test coils/condensers, and to strobe the distributors. I can almost guarantee that 90% of all NORS condensers ( non ford) are bad out of the box new... take a good used ford or NOS and they will be good. Not sure what you're problem is exactly... but you just have to logically troubleshoot it. It is probably electrical. Look at the ignition resistor, are the connection tight, ignition switch, connections tight? Like one said above.. if it is warm that's a tip off the wiper contacts inside the switch are not clean and making good contact. Use a Volt/ohm meter and start checking for voltage drop. There's more to setting up these distributors than just installing new points/gapping and go. Yes, they may run but not well. Bubba's ignition or some like myself that do strobing are recommended. If you test your coil, strobe distributor, and test and install a good condenser I can almost guarantee that it will run well .

I like Sun's old slogan... "Test, don't Guess" How true it is...
Good luck!

I purchased two new condensers from Mac's and could not run the car on either once the car warmed up a bit. I would run NAPA condenser FA49, is their part number for the 37-41 coil condenser.
