More issues, looking for some guidance before I have the truck towed to my local shop.
A few months back when the fuel sender unit was replaced the battery was also replaced with a new AC Delco unit. I haven’t driven the truck much between then and now, probably once every other week. Yesterday I went to start it up, and no go. Just a click, then nothing. Lights and radio on, but no crank. I put a booster pack on it and was able to get it started up. Drove around the block a few times, put it in my driveway and put a trickle charger on it. Battery trickle charger said the battery was sulfated, and it went into de-sulfate mode, which would take minimum 10 hours.
This morning the battery appeared to be ok. Trickle charger said it was charged, but the truck did not start. Even with a booster pack. Lots of warning lights- check engine, 4lo, CEL, Check VSC, etc. One click then nothing. I then tried jumping it with my Volvo but same thing, one click and it wouldn’t even turn over.
This evening I swapped batteries with my Volvo as a test. The LX battery started up the Volvo without any hesitation. The Volvo battery did not start the LX. Same thing, one click then nothing. Put back on the trickle charger and it looked good, no sulfate warning and the battery appears to be charged.
I get 12.7V between terminals, and I think the same between the battery and the starter, but to be honest I’m not sure I have located the starter correctly.
I read perhaps it’s the immobilizer and have tried a generic Lexus sequence of locking/unlocking with the metal key, but no go.
At this point I’m not sure what else to test. I hoped to get it started with the Volvo battery just to drive it to my local shop, but I can’t even get it started. I hate to call AAA but that’s the next step. Camping trip planned next weekend, assuming I can get this sorted!
Anything I missed? Any other thoughts? Thanks!

are you sure it’s not a bad starter solenoid?
