For some reason I can not for the life of me upload the pictures when it came into the shop, preflood. And seem to have the same issue while continuing this thread. So now you get to rear this and just use your imagination until I figure that out.

Cool so now we have one heck of a build, maybe. The good news is I get to start off from scratch, I'm not taking a prized, clean daily and turning it into a track rat. We are pretty much turning a rat(dead rat) into to track rat

So we have the car, we know the potential risk of damage, but we also know there's INCHES of long term standing water in the vehicle and it has no power anywhere, duh because its flooded.

I start the LONG and I mean LONG process of extracting nasty stagnant water from the interior and removing the rear seats so I can sneak into the trunk and pop the trunk open. I threw away all my clothes, you can not imagine the amount of growth and I've never seen mold like this before. Some of it was mesmerizing, maybe a mold spur high IDK. Under the rear seats looked like the thickest spider web design imaginable , everything else was just plain nasty.

To my surprise there was an insane amount of standing water where the battery is, nearly half way up-then I remember there is no glass in the car.
We moved shops and when out of town for a few weeks-this time made sure to keep the vehicle inside and out of the way from day to day business and well health and safety hazard.

When we got back in Sept of 2024 it started our slow season, which means I can step back from the hands on operation a little more and spend time on the vehicle. Time for the full interior removal, everything came out minus the dash, steering and any electrical under/behind the dash.
I knew right away this was either going to the scrap yard or I was going to have hours of wire diag and trial and error until we could get power back in the vehicle and start our diagnosis-removed fuel system is shut off.

The most concerning things to me were the main battery cable from battery to vehicle was rotted away, literally there was no connection point anymore going through the chassis. The JBE and all surrounding items were horribly corroded and this big relay under the passenger carpet was rotted away along with the wires going to it - its the fan relay.
Repaired the battery cable and connection point, repaired wires and replaced the relay, threw a known(okay, not great) battery in there-not connected and then began the JBE trails.
I wanted to see if it could be saved so I began removing every main connection and depinning the harness from all four connectors. Some were rotted away so I repined those and cleaned everything else and put it all back together. Reconnected the battery and plugged in the key, nothing.

I pulled the key holder out and found, you guessed it more corrosion. Needless to say I cleaned everything in there and the traced back to the FRM and CAS and found the same thing and repeated the process. I WILL GET THIS THING TO POWER ON. Placed the key in the slot, click and it accepted the key we get power
