Hello Tacos,

I had the same issue on my '07 987CS and drove me nuts as you turn the key and everything on the dash lights up but the engine completely dead (not even a click from the starter). I removed the starter just to find that it was ok, the relays were fine as well..

The positive cable from the battery goes into a power distribution block (with large fuses) this distribution block it is located on top of the glovebox.

However, the positive cable from the battery attaches into a Mickey Mouse designed connector on the firewall (battery side) and this unusual connector has radial metal contact stripes that attached (by friction only) into a rod that goes through then firewall
this rod comes from the power distribution box.

After we finally ID the culprit, we found out that the positive cable with the funky design was discontinued by Porsche.. therefore we just cleaned the rod as much as possible and cleaned the 'radial connector' on the positive cable with electric cleaner, applied dielectric grease and reconnect the cable.

This solved the issue for me, you may want to check it up, it's free just a bit of time to clean the connector.

Good Luck!
