I only have the one key at the moment. The key appears to be fully functional; i.e. unlocks and locks the car. The owner had it in for service at another shop after having it in storage over the winter. After the service they drove it around for several days without problems and then stopped for a gas fill up. After filling up, the car would no longer start.

When the key is turned to the start position there is a rumbling noise from the front (perhaps the fuel pump or brake booster turning on) and then all noises cease a few seconds later. There is no response at all from the starter with the clutch depressed.

I used a diagnostic unit (Durametric) and connected it to the car. With the key in the on position I explored each available module. There were no faults in the DME module. I found the fault described above, along with others in the Alarm module.

The battery has been pulled, given a full charge, and then returned to the car with no positive effect. I was hoping there was a fuse or relay I could test at as opposed to going to the starter itself as it seems rather inaccessible.

I'm going to get back to that car tomorrow night and will attempt to follow Porsche's diagnosis instruction. However I don't have special tools 9616 and 9617 (these are the recommended test tools) so I'm not sure how successful I'll be.

Any suggestions on other troubleshooting I might do will be appreciated.

Thanks!
