2000 Boxster S, 6 speed, 75K miles.

I drove it around the block to my garage in the back a few weeks ago and when I went to start it again it wouldn't crank. All the. dash lights appeared to be OK, the windows and lights work fine.

So, I started snooping around here for clues on what to look for. I found a lot of good information but
I still haven't identified or fixed the problem.

So far I've checked the battery voltage, it's 12.8 volts. I checked the clutch pedal switch both by bypassing it and checking it with an OHM meter and it appears to be OK. I checked all the fuses. I bypassed the starter relay with a jumper between pins 87 and 30. When I did this it would crank but not start when the ignition switch was turned to the start position whether or not the clutch was depressed. I also checked the starter relay itself and it appears to be OK.

I removed the circuit board from under the driver's seat to check for possible water damage and it appeared to be quite dry. Since I had it out I went ahead and gave it a bath in isopropyl alcohol, let it dry for a day or two and then put it back together.

Still no luck.

Any advice on where to look next would be greatly appreciated.
