2013 Chevrolet 2500 HD -Starts once then won’t crank

Question

I have installed Evo All SN 001A07 468692 with T-Harness THAR-GM4 withRM942 remotes and MYCAR using hrn-11rs-01.

The factory remotes work as well as the 942.  

The truck will start once using the remote start and then just light up and “click”.  If I unplug the module it will work again.  

From reading through the messages here I believe the issue is that I have flashed it too many times.  

Any help would be great

Hello,

 

I will submit your module for reset, it can take up to 24 hours.

Once you re program it , please run the same test as you did except leave the mycar unplugged.

 

Thank you.

I was able to reinstall the system listed above.   I followed your instructions to not install the MyCar.  Everything works as it should now.   I then plugged in the MYCar with no success getting it to work when the RF antenna is plugged in.  I can switch them and they work.  I am unable to get both to work together.  any help would be greatly appreciated.

Thank you for running that test. So you will need to pick one or the other, they cannot both communicate at the same time as it jams up the evo.

Best regards.
