Issue:
-swapped battery on truck that worked fine before(battery was shot)
-motor cranks but will not fire
Details:
-truck ran perfectly fine 5 minutes before swap as well as multiple times throughout the past month(battery was on a charger when needed as well as the battery being from 2019)
-instrument cluster works fine - nothing strange like flickering/etc
-rpm gauge moves during crank (as far as I understand, that means the crank sensor is working)
-no red lights for security
-no alarm lights
-radio works fine
-headlights work fine
-all accessories work fine
-3 codes from a check engine light: failure to communicate with HVAC, failure to communicate with radio, failure to communicate with security module
-fuel is getting to the plugs
-no fuses blown
-pulled TIPM and tore it down: nothing corroded nor burned/damaged in any way on the board
-there was some green corrosion on the metal clip connector outside of the TIPM where it connects but it did NOT run inside at all
-not equipped with WCM(regular analogue chipped key; manual hand pulled locks on doors/hand roller windows/etc)
-if key left in ignition(not turned in any direction), you can hear a click every few seconds from somewhere under the battery
Not sure what I did wrong. I have pulled the old battery many times over the years without any issues except losing the clock. Currently, I do have the TIPM pulled completely out of the truck. I have the positive and negative terminals zipped together so they touch for over 24 hours. Will see if this TIPM hard reset works. Another thing I want to try this weekend is pulling a coil and using a tester to see if the truck is sending spark(I assume it is not hence why the truck will not start).
I had it parked for a while due to a control arm bracket rusting away. That has since been repaired properly which meant it was time to get the truck on the road again. Again, the TIPM visually looks great. No corrosion in the box, male prongs, female plugs, etc. That clip that comes outside the box had green corrosion but only where the screw/nut was.
The only other weird thing I can think of was the far right of the OBD II port had green corrosion - the final slot. The OBD II connects \========/ this way if you want to visualize it and not sideways or /=======\. The last slot at the bottom had some green crust. I did clean it off and my OBD II works fine, so not sure what is going on there.
Just looking for any tips or ideas at this point. Hate the junk the truck since it has been running very well.
