Again, if the TDR clicks on everytime you turn the key to the start position there is nothing wrong with the control part of the starting system. My best advice is to buy a new or salvaged TDR socket.
Got a used tdr on eBay. Seller said it was checked. Put it in and got the same result. Clicks when I turn the key but nothing else. My guess is the part must be bad. I’ll have to get a new one and see what happens. I assume there’s non oem parts that will work. If the plugs and schematic is the same it must work the same.
When you need a proprietary electrical part for a C5, and the new part is still available from GM, I've found it prudent to buy the new OEM part. Disregard that advice where the oil pressure sender is concerned!!!

The socket is working if you can Hotwire it isn’t it? The wires are still connected. Not trying to be a pain but if it was disconnected it wouldn’t start.

the one I put in was oem. Got it online from a vendor but still the exact same relay.
really trying to avoid going to a shop to get it fixed.
By jumping the red and violet wires you are making contact where the wire is crimped to the female terminal of the TDR socket, you may have corrosion or poor electrical contact at the TDR prongs and female contacts.
It's the TDR socket, I don't belive you can purchase a new one, you will have to get one from a salvage yard like Vettenuts. Have you inspected the contacts in the socket and verified that the prongs in the relay are matching up with the female contacts in the socket?
I did a search for Theft Deterant Relay connector and had success, some even had the correct colored wires. Did you inspect the TDR socket for corrosion of the female contacts, some people have had water drip on the TDR when the drain udders got clogged.
There was no signs of water. I cleaned that udder a couple of months ago and it’s been working fine.
found this on eBay. I was searching for the connector and should have looked for the whole thing.
it looks like it’s been replaced before so I’ll take it apart and splice the new one in there.
I wired that in and same problem. Tdr clicks when I turn the ignition, starter works when I jump the wires. Not sure where to turn, the battery is charging. I’m going to disconnect it and see if doesn’t reboot something.
Any ideas what it could be?
I don't know what to tell you other then to ask you if you are absolutely sure that the relay you hear is the TDR. If you insert meter leads to the yellow and yellow black stripped wire of the TDR, do you have 12v when the key is turned to the start position of the Ignition switch?
I checked where I spliced them for voltage. Put the clips on both ways. None.
I held the tdr when I turned the key and nothing.
the noise was coming from the one next to it, I could feel it when I turned the hey.
Should I check the ignition again? I cleaned it but there may be a wire loose or something.
You can clip on to the yellow wire and a ground to check for 12v when the key is turned to the start position. This test will tell you that 12v is leaving the Ignition switch going thru the Park/Neutral or clutch safety switch if it's a 6 speed manual The second measurement is clipping the meter lead to the yellow black stripped and the supply side of a fuse in the fuse box, you should see 12v when the key in the on position. Verify which test does not show 12v and we can proceed from there.
The one voltage check is to place the meter lead to fuse 14 of the interior fuse box and the other lead to ground. Turn the key to the start position and verify there is 12v, if no voltage is present then its the contacts within the Ignition switch or a loose wire.
C1 on the TDR is always 12 volt
C2 on the TDR is 12 volt when you put ignition key ON.
A2 is 0 volt
C2=A1 = on the DR is 12 volt when you put ignition key ON
---
When you press ignition key to START:
C1= A2 --> 12 volt(batt voltage)
A1 is grounded by the BCM and voltage drops from 12 volt to 0.1-0.2 volt when TDR relay is energized
