HELP - My C5 wont start / crank :(
Can somebody give some advice ?
Started with my ignition switch was bad (bad connections), so I replaced it.
After that the car would not start anymore.
Tried to put the old ignition switch in again, still wont start.
Battery is ok, 12.62 volt.
No codes.
Fuse 14, 50, 52 OK
Replaced the starter (that was my first guess).
Replaced the Theft Deterrent Relay.
VATS is deleted (resistor) - also tried to disable it in HP tuners.
It's clicks, but wont crank.
I have tried the 3 x 10min re-learn, but the security light does not blink.
When I JUMP the Theft Deterrent Relay RED & PURPLE wire with the IGNITION KEY in the ON position, it's starts and runs.
There is no volt on the yellow wire, on the Theft Deterrent Relay, with the IGNITION KEY in the ON position.

Sorry for the incorrect info in your other post about the voltage being at the yellow wire in the ON position of the ignition switch. Voltage should ONLY be on the yellow wire in the START position.
Did you verify fuse #14 is good?
You can check the voltage at fuse #14 with the key in the START position. BOTH should be battery voltage as well at the yellow wire in the Start position.

Took fuse 14 out, and checked for Voltage, in start position.
Also checked yellow wire on TDR, in start position.
NO VOLTAGE.

The ignition switch is new.
Tried the old one again (had a loose connection - but worked).
The car can't crank, with the new or the old ignition switch.
Maybe it's the wire to the connector ? What color, is the wire, going from the switch to fuse 14 ?

Sooo - problem solved.
Took the old ignition switch and cleaned up the contacts.
Installed it, and the car started right up.

Connections was bad, loose spring tension and overall quality was bad.
Cleaned up the contacts., and gave the springs some tension.
I think it will work now, but have not tested it.

Glad to see you got the car up and running! I'm waiting for the storm to pass us by here where I'm located so I can also rebuild my ignition switch.

Just wanted to chime in and say thanks to Bill for that post on the ignition switch repair. I had to track down some electrical gremlins in the wife's C5, and that switch proved to be part of the problem.
