Hi,

I am having an issue with my 1977 911 S in that I can't get it to start. It has approx 188K miles

Last Monday, I had the car out for a drive and out of nowhere, the car died and wouldn't start. It seemed that the car had electrical power as the radio still worked and it would crank but not turn over. I assumed it was a fuel pump fuse, relay or the pump itself.

I had it towed home and the car has sat for the last week. I put it on a trickle charger on Friday night and borrowed my friends multimeter today to try and diagnose the problem.

First thing I did was confirm that the fuel pump fuse was fine, it wasn't broken and seemed to be ok. I wanted to lower the windows, so I turned on the ignition and sure enough, I could hear the fuel pump running so I started the car. It did start and ran for a number of minutes before dieing again. At this point, I try to turn it over and again, it is cranking but not firing and the fuel pump isn't running.

I'm thinking it is a battery issue now but I'm kind of reaching. I set the multimeter to 20V and tested the battery and it showed around -13.5 but I don't really know if that means it is ok.

Any ideas what I can check next?
