Ok so on monday me and the wifey went wheeling and we found a river and were driving through it and having fun for a couple of hours. Then I let her drive, and me being a dumb *** decided too let her drive with out me in the car. Well needless to say, she found the one hole in the river too deep for the Jeep. The front end was completly submerged, the entire inside of the jeep up to the windows was full of water, and all lights started coming on randomly. Well we pulled it out, jumped it and finally got it to start. I think it was only running on like 3 maybe 4 cylinders. All the lights slowly started going off and working normally, and the dash lights and gauges all started too work. Well on wed I took finally got under it too work on it. I replaced both the diff oils, the t-case, the engine oil, pulled and cleaned the spark plugs, and flushed the radiator. I havent flushed the trans yet due too not being able too find the right tranny fluid in Japan. So my questions for you guys is what else should do?? It still feels like it running on less than 6 cylinders, Maybe there is water in the gas tank???? Also how important is it too use the mopar tranny fluid???? The airbag and ABS lights stay on???? And I read somewhere that I need a special additive for the rear diff???? Thanks so much guys for the help in advance, I really dont know much about jeeps. Always have had old K5 Blazers and now Japanese cars due too being in Japan!!!!

 

Well the best thing to do after flooding a vehicle that much in water is to not start shortly afterwards and have it towed so you can dry it out before you start it, just like if you drop a cell phone in water you want to take the battery out and dry it off before turning it back on as a example.

But since it has already been done will go to the next step i would be looking at dealing with the abs and airbag light.

It can be one of two things its very possible the the abs module and also the airbag module are fried since you started the vehicle with alot of the electronics were still wet on the inside causing them to short out the airbags them self are sealed so i wouldnt look at those being bad just he module.

We get a few vehicles in the shop around flood season and typically the abs module,body control module,airbag module and ecu are typically fried.

As for running rough its very possible that the ecu is shorted out also causing it to run bad, but there are also other things that can cause this but if it was running good before this happen then its a good chance it is.

I would say the distirbutor could have moister inside but that should be dry already if its been a few days but something to check.

Buts its really hard to say how much damage could be done after a vehicle has been flooded the best thing to do is just check everything over and see if you can find some cheap parts on ebay to get her back in order.

 

oh and the rear diff aditive is only needed if you have the factory limited slip or aftermarket lsd if not then just you standard 75w 90

 

I dont have a distributor, mine has coil packs. Could those be bad? What about water in the fuel causing the spark plugs too foul out immediatly??? And as for the diff I'm gonna check it tommorrow to see if its limited slip, if not I already changed it and put 80w90 in it. Is that ok or do I need to change it to 75w90???

 

nah 80 w 90 will work fine.

As for water in the gas there almost no way the system is almost fully sealed minus the gas cap which if it was secure then your good.

The best thing you can probally do is remove the electrical connectors and have a can on air and make sure all the water is out of all the connectors.

If its still running bad after that then you might have some fried module or ecu.

 

get a snorkel...

 

Spark plugs don't foul because of water.

 

Yeah I'm working on a plan to build a snorkel, but I have ABS so trying to work around that one, I'm heading to the shop now to first do a compression check, if that's OK then flush the trans and maybe drain the tank and put new gas in it. I'm gonna see if they have a computer to read the code. I'll keep you guys posted. If any one else has anything I'm so open for suggestions and thanks so much guys for all the imput and help!

 

heres a link for a snorkel... http://www.ausjeepoffroad.com/forum/...ad.php?t=83065 its a aussie one ,so jeep is right hand drive.... think it has abs ,cant remember... good luck with ya jeep mate...

 

Ok just got back from the shop. Didn't due much due to lack of money, but checked the compression. 160 all the way across all 6 cylinders. So that's good but could it still have a bent piston rod? I don't know if it'd still have good compression though??? I had the mechanic at the shop hook his computer up too it, and at first it said that it couldn't connect with the computer. After he messed with it and tried some other things he got it too pull 3 codes: p0122 throttle/pedel position sensor/switch a circuit low input, p0080 Exhaust valve control solenoid circuit high (bank 1), P000c (0,0,0,c), Please refer to relevant technical manual.

What do you guys think? Replace the ECU???

 

I think you found your answer, sounds like a tps, and oxygen sensors, other than that just like everyone has suggested just clean your connectors at the pcm, engine harness etc. and change all of your fluids , should be good to go!

 

Yes, captain is most likely right. Clean up all electrical components and you should be good to go. Best of luck, you are a lucky man. lol. I can't get the wifey to drive through water. Maybe it is for the better. lol

 

Ok so you guys think the ECU is ok? I'll look into getting a new TPS, and you think the O2 sensors are bad? Not sure what the exhaust control valve is that's what im confused about. And the thing that got me was that when we hooked the computer up at first it wouldnt connect when we went through the chrysler option, but when we just went through the OB2 option we got those codes.

 

It is just to hard to tell with so many options left. BTW if you do come to the ecu. I have one out of a 96 that I am parting out if that helps.

 

I think that the newer jeeps, 99+, take a diff computer from what I can tell. And also I might have too find another one out of a RHD jeep not sure yet. Damn I really dont wanna replace the ECU first and find out thats not the problem. Ugh I hate being in Japan and not having access too imformation, tools and parts!!!!
