katrina put water over the roof of my 99 trans am. could water have gotting in to the gas tank. also what all should be done to at least crank my car again.

 

DO NOT start the car, it will trash the motor. You are going to have to change all the fluids, get all the water out, and inspect everything to make sure it's all fine. pull the heads off etc. etc. hopefully you won't need to rebuild but it's possible.

 

Sorry to hear about that.
First drain all the fluids and I mean all.
Drain the engine oil make sure you get all the water out.
Pull the spark plugs out.
And when you are ready to crank I would crank it over a bit.
Then once you get the water out from the top put some marvel mystery oil in and let it sit that way it will loosen up the rings.
I would also flush the engine with some 5 minuite engine flush.
You might want to take the valve covers off too and check for water and other stuff that might have worked it's way in.
Then the transmission drain the pan let all the water out.
Same thing with the rear end.
Then you have to drain the gas tank.
You can drain that by removing the line at the filter.
Same thing with the power stearing.
Disconect the lines and let it all drain out.
Everything has a vent on it thats how the water will get in.
Other that that just make sure the wiring is good and dry.
That way you don't kill anything.
Dam that's bad you will have to pull the whole inside apart and clean everything.
I'm sure somebody else will chime in too.
Best of luck with it.

if water was over the roof of your car from a flood water in your gas take would be kind of low on my list of things I would get to make the car start again. I'm assuming you havn't tried staring it since you get it back hopefully. First I would do is replace the pcm, plugs, wires, coils, and batt. Drop the tank drain and clean it. While the tanke is out unhook the fuel rail from the both the feed and return lines. Take some air and blow out all the old fuel and water that might be in the lines. Next take your fuel rail and injectors off and take them to a shop to have them cleaned. Put in the new batt. ,before you try sining the engine over with the start spin it by hand to make sure it isn't locked up, and see if the engine wills spin over. if it does keep doing it for a whiel and shoot out as much water out of the engine as possible. Finnaly put everything back to gether and see if it will start. I have a good feeling it won't. I don't kow where in MS you are but I'm assuming you were in the part that got the worst flooding with all the human waist, toxic waist, dead bodies, and god only knows what was floating aorund in that water. So it was probably prettty corrosive and probably destoried your entier electrical system. Wiering harnes, connectors, sockets, sensors, ect. Your probably going to have to replace nearly everything on the engine just to get it to start and run somehwat normaly. somewhat normaly. Now lest talk about tranny. Replace the fluid and probably like engine you will have to replace all sensors and harness. Replace the differental fluid and hope to god nothing rusted together internaly inside the engine, tranny, or rear end. And assuming you can get the car to run again you are going to have to replace the entier, and I mean entier interior. Plus all that salt water can't be good for the body of the car. So it will probbly start rusing horribly with in the next few years. Not trying to rain on your parade or **** you off, I'm sorry for what happened but I doubt that car will ever run again and if it does my advice is to sell it as soon as possible. But that is just my opinion.

ps like other people have said drain all fluids and refil them

 

UPDATE:::

Alright guys here is what it is doing now! IT STARTED!!!!

It will only run when we put gas directly into the throttle body? Seems like the injectors are not working properly, but it is starting and sounds good so far???

Any Suggestions will be greatly appreciated!!!

Thanks allot

 

I would say replace them completely all of them. But you might be abel to get away with just a good cleaning

 

I'd be weary about that.......I was thinking that you probably should've done the stuff that those guys suggested....for some reason I would never feel at ease driving around a car that was up to its roof in water without taking everything apart step by step.

 

I don't think you need to go to the extent of replacing all the plugs, wires, coils, and every other piece of electrical equipment on the car right off the bat, but definitely everything should be CLEANED & DRIED thoroughly. It'll be a real P.I.T.A. to do, but you'll want to make sure that all the stupid little electrical connectors here and there have all been dried out, and make sure they aren't beginning to rust or corrode (maybe using some dielectric grease on them might not be a bad idea?)

Ugh, that's such a shame though. Good luck getting her cleaned up dude.

 

Something tells me your opti may be done......

 

He said it's a 99 so its an LS1.
No OPTI spark makes things a little easer on him.

Damn I missed that part......I was looking at his sig....

 

Draining everything and replacing all the fluids would be the least of my worries . . . I would be more concerned about all of the electronics in the car

I know most insurance companies will automatically write off a car that was submerged in water because of all of the problems that can/often do develop from the electronics

and tearing apart the interior to dry out it out right

wow . . . I feel for you pal

 

sorry lunch box but no insurance.
i apreciate everybodys advice but im not to worried about the electronics or interior. my main concern is will it run and keep running. no need to waste my time on anything but getting it running. ill spend good money on other stuff if it will run. sorry not trying to sound like dick just stateing the facts.

 

If you have no insurance there is not much to lose. After getting all the fluids clean, it may give you reasonable service. It just may not be like it was before the flood.

 

Here's a bright side for ya-

I flooded a 77 monte about 15 years ago. The nastiest, smelliest stuff I ever saw came out of the cylinders when I pulled the plugs and cranked it. Must have steam cleaned the engine inside and out on startup or something. It probably picked up 20 hp and a couple hundred RPM of redline, then I ran that thing like a dirt stock for tens of thousands of gravel road miles without a whimper. Oil always turned nasty before the flood, always clean afterward. Maybe you'll be so lucky!
