Took the '74 to the Spanish Landing concours on Saturday. Car ran flawlessly. Drove up the coast later that day, car ran flawlessly. Stopped for pizza and drove some more, car ran flawlessly.

Parked in my driveway to unload stuff. Got my stuff out and went to pull it 10 feet forward to park.

#@%&! Car won't start!

I get to be first
has your fuel pump been relocated? vapor lock? I know the weather is awesome out there but that sounds like quite a bit of driving
good luck

That's a good car. My TOB arm gave out a couple blocks away from home while coming back from Monterey. Stuck in second, I kinda, sorta rolled through a 4-way and pulled into my driveway.

It's a 1.8, correct? I will bet on the fuel pump relay on the battery tray. I had the same problem with mine for years, and the damn thing would always start right up after it rolled off the tow truck. I finally replaced the relay just to rule it out, and I have been good ever since.

$@!& 10 more feet.

That's what she said.

Broke down in your driveway? That is not fair!

Trust me, it is better than breaking down 25 miles from home.

Beats getting a DUI in your driveway (in L.A., ~25 years ago....)

Posted by: euro911 Aug 25 2015, 04:51 PM

... or 92 miles

Haven't had a chance to take a look yet to see what's up. Seems like the battery is dead.

But it's a new battery and alternator (installed last year).

Yeah, I agree, my driveway is the second best place it could have broken down.

Never leave home without AAA.

Won't start?
Does it turn over?



Either way, it'll probably start now.

Mike -

If it's a dead battery, with a known good new alternator/rebuilt ... & not the fuel pump in the engine bay vapor lock & relay issues noted above ... then probably the voltage regulator.

AFAIK they're still available new from Bosch, since the same was used on 911/912/930 IIRC & they still support the tail draggers.

I went to SD & back for a long weekend in mine, then the clutch cable snapped when I got home. Back then my guy Hans Imports was 1/2 a block away, & he sent 2 guys & we pushed it over, up & into his shop!

Gotta Love 'em when they get you home!

Nope, didn't even turn over. Lights wouldn't even come up. Radio worked and dash lights would come on, that's it.

But, you were right. Started right up today on the first turn of the key.

You need to start looking at what the conditions where when it would not start, or even give you an indication of electrical power on the day it would not start etc. and the conditions where it would.
1- heat soak - heat build up can cause electrical connections to no longer carry power. Check the connections around the battery especially close. As they cool, they tighten up ever so slightly.

Maybe others can add other things.

It got hot.

My car does it a lot.

I still say fuel pump relay. BTDT.
