2005 Dodge Viper SRT-10
Previous owner removed TPS sensors from wheels. So, I went into dash to disable TPMS module to see if the Low Tire warning message could be removed. (it could not)

I reassembled everything and when I try to start the car...ignition on, fuel pump on, gauges power up, push clutch all the way, push start button.....nothing.

Here's the diagnosis and tests I've done....

No engine codes
Battery is fine output 12.6 volts
Ignition works, fuel pump, gauges power up
Clutch Pedal Position Switch has connectivity from push start button connector
Starter Relay tested and works
Relay Circuit tested and works
Starter solenoid tested at PDC and engine cranks, starts and runs. (I'm bypassing ignition and clutch switch and push button)
Start button has connectivity when pushed. (Removed from vehicle)

I'm running out of options and it is nearly impossible to see further into the dash to see if there are opens or shorts, loose, exposed wires etc.

It may be time for a fresh set of eyes to look at your Viper.

Have you considered contacting Alex at ADM Motorsports in Eustis, FL ?

This would certainly be my suggestion as I read through your post as well as your previous posts concerning this situation.

Best of luck !!

Will do. I used to live in Orlando and have been to the shop.

I looked at some of your previous posts and this one. It sounds like you have done a lot; including voltage measurements. One thing not mentioned in your summary post above is, do you know what are the components that are not getting battery voltage during the conditions when the car "won't start?"
