Lights, But No Start, Ignition Switch? Clutch Bypass?


Recommended Posts

I have a 1998 Boxster that hasn't been too well-cared-for and it recently got rained on in one of our monsoons (when the water comes down sideways). The windows had been acting up lately, but the real problem is that the CAR WON'T START.

The fuses look ok, but the relay (bottom left of the bank behind the fuseblock) makes a clicking noise. Is this the starter relay? Is this the problem?

When the key is inserted, everything lights up normally, but there is no turn-over of the starter motor. Is it possibly the clutch engagement? Can I bypass the clutch to start it? To see if that's the problem.

Lastly, I've noticed that the ignition switch is a common failure. Does this describe an ignition switch failure?

My tendency would be to replace the switch and hope for the best, moving to the relay and the starter motor after that. I'm hoping to avoid a costly tow to the dealership. All thoughts are appreciated.

Reach under the left hand seat - if it is wet there then you likely have a ruined alarm/central locking/drive block control unit.

Also, take your battery out and have it tested at an auto parts store.

Do you have a recommendation where to get one of these? Is there a way to waterproof it?

You did not say if it is wet under your seat.

That controller has your driveblock and alarm codes so if it is replaced it will need to be re-programmed to work with all of your keys and your DME.

Any good shop with a PST2 or PIWIS tester can do that once they get the authorization codes from Porsche.

Before you go to that expense I suggest you have a good shop (independent shop here in the US are usually less that half the expense of a dealer) with a PST2 or PIWIS look at the car and confirm that the alarm/driveblock control unit is faulty.
