911 SC just died
My '78 SC just died. Running fine has gas. Just quit like someone flipped a switch.
Where do I start? Swapped FI relays, no love. Fuses all good. |

If yes to above then check for spark.

Thanks guys. A couple of times it tried to fire, so I assume it has a spark. It was too noisy where it was parked to hear anything fuel pump/injection related. Good news: it died 5 blocks from a pretty good independent foreign shop with plenty of VW/Porsche/Audi/BMW experience, so I had AAA take it there. If it's not something simple, I'll take it down to my good buddy who's dad was the premiere Porsche mechanic in our little town for 20 something years.

man, the first thing is to take the air cleaner off and check for fuel by lifting the air sensor plate..the first. dollars to donuts the shop does it first.

Do you have a pop-off valve? Did it pop and not seat back all the way?

If it is the CDI you can send it out to be fixed for a couple hundred bucks. Not a big deal.

If it is the CDI I have several sources for used ones that won't even cost that.

The good news? Turned out to be a badly corroded wire between the fuse and the FI relay. Back on the road. The bad news? The shop is a little more expensive that my buddy's "lunch and gas money" hourly shop rate to fix something like this.

AAA, all the way. It was still 1.5hrs of shop time, for basically the same issue. The wire was so badly corroded is was only passing 2.6V's to the CDI.
