Hey guys I have a 1980 Porsche 928 and it only fires up for a few seconds and then shuts down. I believe it’s a coldstart issue. I had this problem years ago but forgot what the resolution was. The fuel pump is working, I’ve done the green wire, new fuel pump and relay and was wondering if it could just be clogged injectors because the cars sat for a long time. Also Is there a relay for the fuel injectors or DME relay if so where do I get one?
