Yes, I installed a new battery and cleaned cables.

 

Sounds like you have some experience with flood vehicles and a good idea what to expect. Good luck with your project! Please don't mind the lame opinions and : Just part of the scenery around here.

As a POSITIVE suggestion: Get the factory shop manual for your model year. It will have all the wiring diagrams and trouble shooting procedures.

Once again, good luck and enjoy your Corvette. Keep us posted on your progress.

 

Thanks, I appreciate the positive feedback. I don't appreciate "Debbie Downers" preaching how dumb I am for buying a flood car.

 

Aww, are you upset that you have a flood car, because you thought it was a good idea?

I'm sure you can spend a thousand years justifying your purchase, doesn't change the fact that you may keep running into problems because of said flooding. Corrosion is awesome.

 

Not upset at all about buying a flood car. I'm actually very happy about it. I'm getting to drive a 2010 convertible for less than half price. You seem to be the one that is upset about my purchase.

You seem like a real jerk, get a life....Probably pissed off at life because you're one of those guys that can't change his his own plugs.

 

I would go on line and buy the shop manual download for $10 or so and then you can find most of your answers. Based on the fact that you have does this many times before, I am really surprised that you are here asking questions from people who know so little about floor damaged cars.

I am in the market for a flooded coupe to turn into a track car but have not found the ne I want yet.

Enjoy your car!

 

Aren't you one who is quick to judge? What are you capable of working on?

You're right. I can't change a plug, but I can swap wheel hubs, install superchargers, make my own fuel system, etc.

I hope you're happy with your purchase, enjoy your corvette.

 

One way to be sure that the fob battery is not the problem would be to put the fob in the slot in the glove box.

 

Thanks,I tried that yesterday...didn't make a difference.

 

The problem is that you don't know which, if any, circuits are affected.
That means your rcdlr could be damaged, or the sensor for the slot, too.

The FOB battery is relatively simple to replace, so try replacing that first.

 

Good luck with the electrical problems. Wiring diagram and going over each connection--especially grounds, seems to be the best starting point. It isn't just water, but the crap floating around in flood water that can cause a problem. Cleaning each one is laborious, but seems to be the best place for you to start. Lots of labor, but you did buy the car for cheap money so I'd say it's worth your time and energy. Hope it works out for you.

 

I'll second this. When a problem is above the head of internet resrouces, Helms never lets me down.

 

Our Son got one of our cars into a flood some years back..... water was up to just above the doors which leaked inside (no electronics under the seat in those days ...). The engine also injested water thru the intake...locked it up. Got the car running fine .... with a lot of work and then a few months later all 4 (unitized) wheel brgs went along with the brakes .. it ended up a "parts car".

 

Wolfgang, I don't think folks here are able or willing to answer your question. Shop manual and tracing circuits is the best answer you are going to get.

Beyond the basic suggestions of making sure everything is clean and dry I don't know of any c6 techs (experienced and competent corvette dealer techs) on this forum. Which is the type of person I would think would be able to provide the most assistance.

Car looks really nice from the pictures you posted and I know you'll work out the issues quickly. Keep us posted!


Also, there is no reason for folks to fight about this or that on these forums. Some folks dicks grow to **** star status behind a keyboard and its really not worth the time and energy to argue on a Internet forum.

 

 

One thing going for you is it was a fresh water flood.
It seems you were able to identify the water line? Thats good--but, remember that water inside a wiring harness will wick--so dont think the possibility of problems stop at the waterline--right?
The dont forget condensation. A lot of electronics now a days are very sensitive to resistant changes and condensation can affect a lot of connections that were above the water line. Even the instrument panel ...I know the hard way:0
A flood car can be fixed--no doubt--but man-- it is work and frustrating. You can't do it with a voltmeter and a ground light. The can bus systems can get really complicated and you can end up just having to throw parts at it. I hope that doesnt happen to you.
My suggestions?
1-Get the wiring manual AND car manual
2-Strip the entire interior and wiring harness out. If the seats are electric or have airbags in them--take them apart.
3- remove the entire dash/instruments and spec them out.
4- once the wiring harness is out--strip the wire back from the connector and see if any wicking has occurred--if it has--get a new wiring harness. If some wicking has occurred to non essential areas-MAYBE you can repair that--MAYBE.
5- Go ahead and replace the throwout bearing--it probably will not last long.
6- check the abs/dsc wheel sensors--they were underwater and they may have been affected.
7- take the starter apart and clean it out--it probably will be ok--just needs cleaning and a little lube.
8--remember seemingly unrelated areas can affect other areas. Thats a can bus system for you--right? I had a Camaro one time that would not shift into high gear ( automatic) because the left rear tail light was out----seriously!
Does the obd 2 port connect to the pcm? Any codes?
This could be a very interesting thread.
GL --you can learn a lot about your car going thru this type repair.
By the way--beautiful car man!

here is a thread that may be of some help

Man, Not one "Run Forrest Run" comment. Some of you guys are slipping...

OP, You have received some good advice. First and foremost especially since you seem to have exhausted your knowledge comfort zone find a competent Vette mechanic that will have a tech II and pay him a few hours labor to scan the car. It will be money well spent. He may even let you watch. He will be able to address every system and tell you what is and what is not working then you will know even know what the intermittent problems are.

I had purchased a tech II for the last couple of C6's I had bought that were branded titles (none were floods however). I wouldn't be scared of a flood as I have looked at many but the prices weren't right for me.

The tech II can save you a lot of effort in not doing a lot of unnecessary work.

Btw, Don't quite understand the comments about fresh water and wheel bearings. One, these wheel bearing are a sealed hub unit and two, I don't see sitting in fresh water flood any different than driving in the rain for continued periods. I have over 80K miles on my rebuilt 08 and have driven in the rain and through deep puddles without the first problem of things under the car getting and staying wet.

The best of luck to you getting this squared away. I've posted some of my projects on here if you want to search my screen name. Last post would have been a year or so ago concerning my latest rebuild.

 

I think you are going overboard with all your suggestions. Just because something got wet with fresh water doesn't mean it has to be replaced or rebuilt. There is no reason to pull the dash apart or strip the wiring harness out. This car got 4 inches of water in the carpet. The worst part was that the water got about half way up the bcm.

These cars are meant to get wet...drive through car washes that wash the underside of your car... driving in the rain...I even power wash engines in cars all the time with no problems as long as I let everything dry out good. It does have power seats and they are working fine, so I will not be tearing into them.

 

You may have bought flood cars before, but these cars are loaded with electronics and sensors. The ones outside the body MAY be ok, but the stuff inside is not designed to get wet, I suppose.

I do not see how water should have gotten into the engine.

Please do keep us posted on your progress. Most of us do not have your courage. It would be interesting to know what you have to disassemble, clean, and/or replace to get the car running reliably.

 

Lol, most people do run from flooders, I run towards them.. People need to realize the differences there can be in the severity of the flood damage. I consider this one to be a very light flooder. 1 quart of water in the engine and 4 inches of water in the carpet.

I would never buy one that has been submerged or even water in the dash. There are a lot of flood cars that only have wet carpet though and they are still totaled out.

I'm going to take your advise if I don't figure things out today. I'm leaning towards the bcm since it did get wet. The water line did go about half way up it. Today I plan on pulling it out again and trying to clean it better, it does have a very slight amount of corrosion on it that I didn't see the first time I inspected it. After that I am going to take it for a drive and see if anything else pops up..Thanks for your post, finally someone I can relate to that sees value in things other people run from..
