No Spark Need Help
 

I have a 75, 911 with a 83 transplant engine. I drove the car to a friends house a couple of months ago and tryied to drive home but the car won't start. The car was running ok prior to not starting. Any way I got it towed home and did the following:
Checked for spark pulled spark wire out and put a new spark plug and grounded against fan housing. no spark I'm also certain I'm getting gas into the cylinders I pulled the plugs and felt and smelled gas.
Had the CDI box sent out and tested. CDI box is good.
Changed out green wire from distributer. Check cap and roter look to be ok.
Bought a new coil.
After all this still no spark. Any suggestions are welcome thanks

I would check the connections in the 14 pin connector in the far rear of the drivers side - back by the taillight but inside the engine compartment. The male and female parts can get pushed out a little and you can't tell from looking at the outside of the connector.

Check the connector to the CD box - the individual connectors can slide out.

Here is a link to an SC wiring diagram. Diagram 1 Page 2 has the CD box. If you take some time and use a multimeter to check for continuity you can chase down the connections one at a time. It is something simple. Finding it takes time.

Did you replace the coil wire? Good luck!

Also...check the rotor to see if it is still intact.
Perhaps it stuck on one of the cap metal parts and when you first turned the engine over... it broke?
