Not sure if this is the place for this or not. But I will be documenting the ls swap journey of my dream truck. I found me a fairly clean rust free 1992 gmc 1500 2wd. Sourced a junkyard 5.3, and a 4l80e trans. I am using a bp automotive harness, hp tuners and a lot of luck. This is my first ls swap so critics please tell me what I am doing wrong.
Took my 2017 Chevy Silverado z71 to the dealer today . Engine was ticking on top end sounded like a lifter tick and slight deeper knock in bottom end . oil presure was all over the place would go from 65 psi to 25 psi at same rpm. I have 44,000 miles. Has anyone else had this issue? With the strike in play who know how long I will be without my truck.

I apologize for the novel, but here we go!
Alright, so 2011 Tahoe 5.3 LMG Flex vin 0, 158k miles, never given me any issues ever before.
Drove it up on ramps last night to get under it to just check everything before I tow a trailer over the weekend. All fine and dandy.
Go to start it to back off of the ramps-dash and running lighter all turn on. Turn the key to ignition and....nothing. If I try to remote start it, I just get an electronic noise.
Took the starter off last night and tested it multiple times at my work (advance auto) and my starter was super dead. Sweet, found my issue, right? Got a new starter. Put it on. Still no crank. No click. No nothing except everything else on the truck acts like it normally would when you turn the key.
I checked connection between the positive terminal on battery and the starter with a multimeter -just fine.
My battery is perfectly fine. Tested it multiple times now. Have a charger. Made sure it's fully charged. Double and triple checked.
Looked at all the applicable fuses I can think ofand swapped the starter relay with the ac relay (they are identical) and it changed nothing.
This then led me to believe maybe the ignition switch in the steering column was bad. Put a new one in today. Same exact issue. It changed absolutely nothing. Everything turns on but no crank and no relay sounds or anything.
Almost thinking that something isn't sending the signal to the little wire connector that is on the starter selenoid (attached to the starter). But I feel like I've checked everything that could block that.
I'm running out of ideas and I NEED (super awesome timing!) this truck to move from Lincoln to Omaha starting tomorrow 😕 ugh
Was wondering if putting 12v constant to that little plug wire on the starter solenoid may skip whatever is not sending the signal, which I guess would just confirm that there's no signal. I dunno. 8+hours into this so far. First time this truck has ever given me issues in 158k miles.
Also, no, it will not start in neutral.
Any tips would be awesome!
