I need some help. After a short ride last Friday, my 911 died as I was pulling into my garage. I tried to restart it and when I did, it ran rough and finally stopped. I have not been able to start it since. I have checked out the CDI as okay, installed new distributor cap and rotor, and checked the fuel pump. The fuel pump will run if you jumper it across the terminals in the relay socket. I have checked the air flow controller and it also operates the fuel pump when you lift the actuator arm, and it stops the fuel pump when you release it. I am at lost as to what else it could be except a short somewhere. I have checked the fuses and wiring at the block but have not found any open or broken wires. The only thing I have not checked is what the Bentley manual calls" a RPM limiter switch". I don't know where this is or if it part of the 911 sc.

If anyone has any additional ideas I would appreciate comments, as I am about to lose the remaining hair I have over this one. Thanks
