'70 911T Died then came back to life

[Marken]

I drove my '70 911T off an on over the weekend with no problems. Sunday afternoon I came out of a restaurant and it didn't start right up like it usually does. It struggled for just a bit but then fired up. On my short drive home and about a mile from home the car basically shut down completely. I coasted into a parking lot. The car cranked just fine but would not fire at all. To me the symptoms seemed like out of gas, however the gauge read about 1/4 tank. I thought the gauge might be off so I walked home and got a gas can. Went back to the car and put in two gallons of gas. Still would not start. Waited about another 15-30 minutes and car started right up. I was hoping it was just out of gas but when I went to fill it up it only took about six gallons. I am a bit nervous driving it now as I am afraid it could shut down again at any time. Any suggestions on what could have happened or what I might check. THANKS!

could be an intermittent electrical problem

Really could be a number of things. I had a similar problem though, and it was crud in the gas tank blocking the intake screen. Being low on gas would exacerbate that problem. Could be a CD box or coil malfunctioning when hot, but I would start with the gas tank.

Thanks. Will check out the gas tank first.

Thanks. Will check out the gas tank first.

I don't know where to find the screen filter on the tank. Is it underneath? Do I need to drain and remove tank? Also, the car has Zenith carbs now. I also looked for the cartridge filter in the engine compartment and didn't see it. See photo. I followed the fuel line to the carbs and see what looks like a filter at each carb. See photo. I probably should remove and clean or replace them while I'm at it.

Your CD box is dying. Your symptoms are classic.

Thanks. Is this something a novice can replace? Are there adjustments to make after installing? Sorry for all the questions.

Also, you can see the CD box in one of the above photos. There is a red wire that is hanging down that is not connected to anything. Do you suppose that is OK? Thanks!

Can a CD box be rebuilt?

I had the same symptoms once and it was the CD box.

Easy to replace.

Don't know what the red wire is... Not coming from the CD just behind it.

I installed a "rebuilt" CD from Parts Klassik recently and am very pleased with it.

Thanks. I will do this and also clean out the fuel tank as well.
