Waterlogged 99 Boxster

Well good news/bad news. I checked the pump power cable when I was cranking the engine and the pump is getting power, so it's not the immobiliser or an inertia relay problem. I also checked the fuel line at the rail and it was indeed getting fuel, so it's not the filter, and probably not the regulator. There was definitely enough pressure to spray me so it should have enough flow to run the injectors.

Well actually that is good news. The more you eliminate the closer you are to a soultion. I would look hard at the crank position sensor, throttle position sensor and the spark system.

yeah I am going to be checking the spark and injectors when I get home. Most likely it is something that is disabling all the cylinders otherwise it'd be running and I'd get misfire codes.

The things that throw codes and the things that do not are hard to reconcile sometimes.

crank sensor takes a crap - no codes
Leaky head gasket - no codes
new gas cap - codes
dirty MAF - codes

Go figure!

Nightly update: Checked injectors and they are getting a timing signal so that's one more part that is working! I'll swap the ignition switch tomorrow, and if that's not it, then it'll be on to the crank sensors.

Slow and methodical is the best way!

One guy suggested doing a compression test of the cylinders. Is there anyway that there could be gasket/valve/piston ring issues that would cause all of this? I had no smoke and my coolant and oil are both pretty clean.
