I just completed some major work (Oil Well O-rings,All Camseal Replaced, removal of interior Mold,New Exhaust,all Vaccum Hose replacement, new battery ). When I started it up after all this work it was idling oddly. I found it was a dirty MAF and brake booster Check value leak.
I cranked it up it if was purring like is should after 2 years of sitting.
Then out nowhere it wouldn't crank. 
I tested the new red top battery and it is fine. I checked the all the engine bay ground I know about and those look good. The Main - and + lines are upgraded to higher gauge wire with no signs of corrosion or damage. The Positive line that runs to the Fuse box is Newish(2 yrs old )
Starter is Newish, It was replaced with OEM (2019) only has ~7-10k miles on it. I checked the fuel pump relays with Multimeter and it looks good. I checked all fuse in engine bay
I did have some door seal leaks that brought water into the car while it sat. I am wondering if there is a ground inside the car under the carpet that might be corroded. I am unsure of the locations I need to look at. Does any one have suggestions ?
This is a video of what the car acts like when I attempt to start it. https://gofile.io/d/PcZBLr
The power drains and no indicator illuminate. Jumpstarts make no Difference. if I disconnect and reconnect the battery after this power drain, the dashboard will illuminate like normal in the until I crank the key to start again.
Please help me get this money pit running .I have had this car 110, 000 miles and I am trying to get another 10 k pleasure out of it
