This is an interesting one. So, the engine will not shut off, but all the warning lights will turn on, but the tachometer goes to 0. Is that correct?
When you say the tachometer goes to 0, that leads me to think a crankshaft position sensor may be failing. However, in most cases, the engine will shut off if that is the cause.
Do me a favor. When this happens and the vehicle is still running, gently move the ignition key back and forth a small amount to see if things begin to work again. If they don't, the can-bus system needs to be scanned.
Here is what I recommend. We need to scan the can-bus. I need to know what code is present or if there are any present. To retrieve these types of codes, you will need to scan the can-bus system. CAN stands for controller area network.
Basically, all the different modules are tied together via a few wires. This type of scan will retrieve codes regardless of the module storing them. This is what needs to be done to determine the correct diagnosis for your vehicle
Here is a link that shows how it's done:
Let me know if that is something you can do or have done.
