Hey. Has a 928 s, 1979 mod :-) It has been a while since it has been started. The problem is: it starts fine but only runs for about 10 seconds after initial boot, when I will start it again it only runs for about 5 seconds, then stops!!
I have cleaned the fuel system until the engine and force driven fuel pump, fuel filter replaced, but the same problem is still there, it will not run! Anyone have a tip on what could be wrong?? THANKS .....

I will take a shot: Fuel pump relay is cutting out. It would be nice to know for sure if fuel pressure is dropping off at 10 seconds. Or fuse 22.

I have replaced the relay, but the problem is still there!

It's starting and running on the cold start injector.
The CIS fuel distributor is not opening the injectors, or the injectors are plugged.

Can you please explain to me how / where CIS fuel distributor is located? How do I clean injectors? Thanks....
