That would be way further down on my list, I think you are on the right track looking at the electronics of the systems first.

Tonight's piece of the car that is working just fine: the ignition switch. On to something else.

Anyone want to buy a 99 boxster? I can swear that 90% of the car works flawlessly!

Man this is really odd. Last thing is going to be spark. To have zero ignitions makes me think something in the alarm system is still triggered or you really do have bad gas that refuses to ignite.

My money is on the crank sensor. It is a hall effects device and subject to failing due to metal, oil and time. I just replaced a bosch crank sensor on a V8, in 96-06 rovers they are a common failure.

In screwing with the ignition switch I was able to observe the alarm operating correctly. I agree with you about the gas, but the gas I pumped out of the tank with the fuel pump still hasn't separated at all.

There are two cam position sensors on the boxster. They are about $90 a piece. not sure if a single failure would do this.

I checked battery terminals and replaced the ignition switch. Nothing!

I attempted to start the car with starter fluid (not the BBQ variety) injected into the throttle body. Still nothing!

The first time I try to start the car it vrooms like it's going to work then immediately goes back to the whir of just the starter.

Okay so if you get an initial 'launch' of the engine then it dies with no further ignitions then I'd really change the fuel filter, no matter how much pressure you think you have. When the filter is blocked it will still seam some fuel through so waiting allows pressure to build up in the rails but after the initial surge then no more gas.

Beyond that I'd say its time for a shop because you're running out of places to look.

I would think the carb cleaner and ether I sprayed in there would have been enough for it to run for at least a few seconds if it was getting a spark. I might have to bribe some people with beer to help me get it up on the ramps to change the filter.
