2012 5.7 starting problems

[JOe G]

My 2012 has 79,000 miles on it, mostly local so lots of starts. On two recent occasions after no problem starting on initial morning starts, and after driving a short distance, I have stopped the engine for a few minutes and then when putting the key in the ignition the key will not turn and will not let me remove it. After setting with the key in the ingnition it will allow a nrmal start. I checked the battery in the key,which was fine, and even started using the key that I had never used but it did it again. Is this most likely the WIN module? I tested the truck battery which is good.

When you checked the battery, was a LOAD TEST performed? You really want it L/T'ed. Also make sure the cable connections are super-good & the grounds to body/engine. I'd remove the battery cables & clean the terminals to be sure. Not being able to remove the key kind of points to a bad battery connection like you were looking at. But it could be the module. Do a youtube search for WIN module and several will come up.



Good luck!

Win Module, its an easy fix - https://youtube.com/shorts/BT99jCOwCBE?feature=share and since its a POS 2012 like mine , you should really be getting ready for a TIPM, lucky its a also a dirt cheap fix https://verticalvisions.com/en/25-products
