Don't immobilize me, dude!

[eltren]

'99 base 986

Backstory: Rainwater flooded the driver's side footwell while the car was parked needing a coolant pump.

Pump, thermo and sundry hoses replaced and good.
Drains cleared and not so good. Water is still coming in somewhere,
slowly. Top is brand freakin new. Ideas?

Most of all, the immobilizer seems to be toast.

The car had been starting oh, half the time after I installed the pump.

Now it won't crank at all. Everything else is fine, as in batt, idiot lights, etc.

So.

How to diagnose definitively?
Can the immobilizer be bypassed allowing the car to operate normally?
If I need to replace the immobilizer, is it a bolt-on job, or...?
If I need an immobilizer, can you recommend a solidly reliable source for a used one?

if it is the immobilizer, you'll need a new one and it will need to be re-programed by the dealer.
Expect to pay at least $1200 on that. I had that happen a few months ago.

For me the top was not new and I had water leaking in through the stitching that held the window in. I went to my insurance company on that one because we had an excessive amount of rain that week. But with a 1k deductible I ended up paying for most of it any way.

Looks like it's out of my hands.
Am in NW Fairfax county, VA.

Far as I know, there's three choices.

Tysons Porsche
IMA
Intersport

Where would you go?

I talked to both Porsche of Tysons and IMA the other day about IMS and other related projects that I am planning to do. Call them and then make a decision. There is also AUTO TOY in Germantown that is a Porsche guru.
Happy Boxstering.
