Default Predator won't communicate with car ECU!!!!

I've had this Predator for about 2 years and never had a problem till now. I hooked the predator to the Diagnostics port and choose real time data. The predator tries to communicate then it says to much sure the car is in the ON position....but the car is running!! Anyone ever had this problem??

Troubleshooting isn't under options. All it has is....pc communication...display serial number...set password...clear password...tool id...show current ticks....buy ticks...about tool....tool status....car tune and send software id

thats an olllllld tool...

have you installed anything aftermarket since the last time you used the predator til now?

sounds like something is tapped into the ignition wires and the predator isn't able to detect that the key/ignition is on....

Yeah, that is old....

Did they weld the cats in on the car?
Was the PCM disconnected before they started welding on it?

Id suggest sending that tool in for a hardware upgrade.
For $99 + shipping, we'll gut it, rebuild it into a brand new Predator that is internet updatable, and has logging capabilities, and works just like a brand new tool.

Thats aside from the fact that there could be issues in the car due to the welding that was done, tough to say for sure without another tool that can try to communicate with the PCM.

did they wire up the electric cut-outs to the ignition wires? disconnect/pull the fuse for the electric cutouts, and see if the tool works...
