New member here and completely dumbfounded
This is on a 2004 Z06 with a Stock GM Battery.
Here are the chain of events and t-shooting:
Turn the key and all power to the car worked fine.
Car would not engage the starter. (No solenoid click)
TDR never clicks, however a relay on the fuse box does.
NOT an intermittent issue.
Troubleshooting:
No codes appearing.
Tried 2nd key that does not get used much, same result.
Checked resistance on both keys and cleaned them.
Bypassed clutch safety switch.
Ensured Battery was/is good and fully charged. (Tested at 2 Parts stores)
Swapped battery with a known good one for testing.
Checked every fuse in car for continuity.
Followed every step in this post.
The TDR:
Is not clicking.
Red wire always 12v.
Purple wire doesnt ever gets 12v.
Yellow wire 12v when attempting to start.
Yellow/black wire NEVER has continuity, attempting to crank or
not.
Cleaned all contacts on TDR relay.
Starter WILL engage manually crossing posts with a screwdriver, however car will try to run, then stops. (I only did this once)
I obviously don't want to throw parts at the car, however I am torn between the TDR and Ignition Switch. And I may be off on that!
Is there an effective way to bench test the TDR?
Thanks in advance!
Barry
