Guys, bringing this thread back to life. The 911 SC has not had my full attention in the last few weeks but I will point out, that 80% of the time, I’m having difficulty starting. I do have my WUR pressure set properly and believe the next thing for me to try is to change the Bosch cold start injector plug end. When I look at the female connectors of this plug, one side is missing part of the spring connection and what is left is suspect. I’m thinking it is time to make a jumper harness to see if my starting trouble can be solved. Is this a standard Bosch injector plug end I can get on ebay or other?
My plan is to run temporary new wires from the thermotime switch to this new plug, which of course I’ll connect to my cold start injector.
Thanks!
