In 2015, I bought my ex a new suburban for her 40th birthday (she was 39). When we got separated she let the au pair drive it for a couple years and then the trans went bad and she parked it on the front lawn like a hillbilly and left it there for 3-4 years. Now after six and a half years I am finally divorced and I wound up taking this truck back. I was thinking I would either keep it for a while and let my daughter drive it for the summer or maybe drive it myself, or maybe sell it. Really not sure.

Anyway she dumped it at a local garage that I did not know. He was a nice guy and tried to get power to it and could not get the interior lights or the dash lights to work. He said there was an ECU issue and suggested I take it to the dealer. I bought my 2022 from them and I have a relationship there. They sent me a video that showed that the throttle body butterfly was green and the tech said he thought it suffered a salt water immersion, which is not true to my knowledge or my kids. So I called the service advisor and we discussed it. She said there was "extensive damage" but that the motor turned freely, and that it would be a minimum of $4,000, not including the transmission. So I said "How do you know there is extensive damage, did you bore scope it?" and she said "No, but it needs a battery, a starter and the fuse box is fried and will need to be replaced." So I said "you guys prob charge $300 for a battery, $500 for a starter, so the fuse box is $3200? What else do I get?" Shockingly, she didn't have an answer. I said basically if you don't want to work on it why don't you just say so? She denied that they don't want to work on it and that was that.

So this is where I am. The reason I am writing all of this is because I am considering having it flat bedded into my driveway and working on it. My plan would be to get a battery, figure out the wiring, and then drain the gas, coolant and oil, replace and try and start it. I would worry about whether i would attempt the trans myself after that point. I am pretty good with cars but this vehicle is complicated by my standards especially from an electrical standpoint, but it's not a job I am scared of. I don't have pics but under the hood it does look like it's been sitting a while and it's possible mice or squirrels got at some of the wires. There is some minor pitting on some of the aluminum parts and some rust on the crank pulley and stuff like that but it doesn't look like it was in salt water. The service advisor said that this condition can sometimes happen from sitting on grass for years and that it doesn't require being dunked in salt water to look this way. There is no rust on the frame or body.

So my question is what do you think? I don't want to scrap a truck that is basically 10 years old with 120,000 miles on it, but i don't want to go down a black hole either. We only have so much time and money at the end of the day and I would prefer to waste neither. Any thoughts are appreciated.

I would probably get a battery and a battery charger. Once it has power i would just work through 1 problem at a time but i have all the time i need and can do the work myself.
Guess it just depends on how much time and effort, dollars do you want to put into it?

all I can tell you is put a fresh battery in it and see what happens, go from there
you didn't provide any photos or anything so cannot even give a opinion
I wouldn't worry about the gas tank, you can throw a bottle of stabilizer in it and some fresh gas and just run it.

I don't know where you or the Suburban are but if close to the coast, the salt in the air can cause some of the described problems. Put a battery in it and check all ignition related wiring that see if you can get it to turn over. If so and does not start, use a small squirt of starting fluid down the throttle body and see if it coughs/starts.

Agree with the above suggestions, get it to your place and take one step at a time, checking things as you go along. I'd probably pull the spark plugs, borescope the cylinders, and turn it over by hand just in case there's any fluid in the cylinders.

And shouldn't it be "...my ex's EX 2015 Suburban?" ;)

If you manually open the butterfly, what does it look like? This really doesn’t look “bad”… it just looks like it needs a bit of cleaning and that’s it. Are any fuses blown?

**I see that the 300AMP fuse if blown. With the new starter and fuse it might be fine…

This is what the dealer service record says

don't go back there, that guy didn't want to work on it.
from the pictures it does not appear to be all that bad, it has been exposed to moisture and has been sitting otherwise standard dirty engine compartment.
put those intake connectors back on, pressure wash it. pull the starter and bench test.
then your going to need a new fuse (the battery top connector, there about $120) and check for any direct short that could have blown the fuse.
as for the throttle body you "could" clean it rigorously or just grab a used one from a auto dismantler/junk yard

**if any of the other battery top fuse were blown that "could" be a reason for no start as well, it's basically a fusible-link

Dealer says the truck smells like fish and looks like it was possibly submerged. I think there is more to this story.

If you have a vehicle that smells like fish and the dealer wrote that it must be a real shit box.

BURN IT.

Or the dealer sees a "sale" opportunity.
