986 non-starting problem (more advanced stage)

[chris7676]

Guys and girls, I would appreciate any good suggestions, the situation is:

• Battery died a while ago after just 2 weeks of non running (that itself was a bit strange), new battery fitted now
• Fuses fine
• Can open/lock the car, all electrics work fine when keen in/turned
• Turning ignition to start results in no action
• ECU and Start relays (1 & 7 in the rear) 'bridging test' allowed me to crank the engine but still not able to start (so ignition switch and started work)
• Replaced these 2 relays + the fuel pump relay but still no action when trying to start.

What could this suggest? Is there anything myself or a car electrician could try or should I just get it towed to a Porsche specialist ?

Thanks, sadly I have 1 key only.

Would I need to get the car to the specialist or just the key ?

[chris7676]

I haven't but it still can remotely unlock / lock it so that little battery is alive.

Rockster, thank you for the comprehensive reply. It's a manual S (2000).

It's unlikely to be the ignition switch as I said I could crank it by test-bridging the relays and then turning the key. As for the wiring - who knows, although the electrics seem to be there generally.

I will need a specialist to get it sorted, but I'm not sure if it's best to get the car towed or just try the key element replacement - if it's the immobilizer. I did open the key and visually it looks all fine there (like new).

The switch worked reliably WHEN the relays were bridged, hence not sure how it could be the offending part, but then I'm not an expert;)
