Totally dead in the water, NO power at all
Hi guys, trying to solve an issue on a buddies 2001 turbo, the car had a dead battery, a float charger was placed for 3 months but is was still dead. Attempted boosting the car via another car and it would turn over slowly. Someone trying to “help” places a charger in a “boost start” mode on in conjunction with the cables already connected from the second vehicle.
at this point my buddy turned it over resulting in a rapid clicking followed by absolutely no power.
We we have tried a new battery, check all the fuses and checked the power distribution block at the fire wall for continuity and all check out.
But absolutely no power, no 4way flashers.... nothing.
He is concerned that the ECU is fried but we hoping there is a disable like somewhere that we have not found.
Any ideas or help would be much appreciated
thanks

Electrical problems are the worst. Is it possible the charger or the jump was hooked up with wrong polarity? Did you check the relays? Can you plug into the OBD port with a diagnostic tool?

find the emergency cord and give it a pull
alternatively, to get to another main power connection, get under the car and connect to the starter terminal

Rapid clicking is a sign that there isn't enough power to activate the starter relay. No power at all means you probably didn't fry the ECU. Check cables for ground and a proper connection on the positive side. Check for a break in the cables or corrosion. Jumping from the rear is an excellent option as mentioned - to bypass the wiring in front.

My 997 is very dificult to wake up at times, but havent had as much difficulty with the 996.
Anyhow, a low draw to zero seems to be the perfect recipe for corrosion. Not necessarily the green crusty stuff, but can be an almost invisible film. Could happen at battery, at ground right in front of battery or at engine compartment.
have u checked voltage to ground?
resistnace?
and yes, jack it up. Make sure safely stabilized, neutral selected and jump at starter terminal or have someone who feels safe doing so. If she engages, u might wven try with key on, double checking neutral if awd.
my 997tt push starts very very easy, but youd need dash to come alive.
id say 90% auto electrical issues are ground issues.
good luck
