Mine runs key or no key jumpered between 30 and 87. Watch out for lots of fuel in your crankcase. When doing fuel testing don't run the fuel pump just start the car. Then you don't pump unburned fuel anywhere.
Try jumpering from 15 to 87. My silber 78 was jumpered this way when I bought
it. Didn't notice it was jumpered until a month later. The 15 connection will
only power the pump when the ignition is on. BTW the jumper had an 8 amp

>When I jump the fuel pump relay I don't hear anything, with the key on or off. I'm guessing this narrows it down to the fuel pump? It just seems odd to hit a bump and have this happen. I checked fuse 43 and it was o.k.
Every 928 owner is REQUIRED to own a 12 volt tester.
1) Check for 12 volts at terminal 30 of relay XX. If you have 12 volts, insert a jumper to terminal 87. (Note - It is a very good idea to have this jumper in the glove box at all times.)
2) Remove fuse #42, twist the legs very slightly, and reinsert. Check the
3) If the pump doesn't run, check for 12 volts on both of the tiny dots on
the end of fuse #42. If you have no power on fuse #42, there is a problem
behind the central power panel.
4) If you have power on fuse #42, but no pump noise, remove the cover under
the rear bumper cover, and check for 12 volts on the red/green wire. If you
have power on the red/green wire, check for ground on the brown wire. If
you have 12 volts and ground on the pump and it doesn't run, replace the
pump. I doubt that both pumps died at the same instant, so you probably
have a power problem.
