Looking for some help here. Roughly a month ago I started noticing that when I put the key in the ignition and turn it over the truck would not start. I would take the key out and put it back in and it would start.. It would still work on occasion when I push it in hard to the right. I have not been able to start truck at all now so I have taken out the EIS module (black Box) and now it seems to not want to go into the ON position to even use a OBD scanner/software to scan it. I fear I may have put it in a immobilization mode? (is that possible)
Is there a fix to the module that anyone maybe familiar with? I don't want to get a new module and have to program it.
If you have the EIS taken out, you can carefully open the plastic cover from connectors side and look over the 3 pin PCB soldered connector for the coil.
Sometimes this connector needs to be re-soldered back on PCB side as when you lift up the PCB this can remain inside the plastic cover
Seems like the 3 pins are connecting we used tin foil to test that. Is there any way to turn the electronics on so we can run the scanner or just to get it on the ON position?

First step ( after checking the main battery, water in SAM or CGW...etc) is to connect a decent scanner for Actual Values regarding Drive Authorization, key recognition ( you can try another key as well ) on EIS - for this EIS only need to be connected into the car harness - also this harness should have voltage...
