I agree from watching your video that sounds like an electrical problem. My suggestion is to take it to a Nissan dealer and run a diagnostic. Good luck.

 

Damn, this reminds me of my hydrolock situation about 4 years ago... hope yours is only an electrical issue as mentioned above...

 

Dayum! Sorry to hear that bro . Hope everything works out for you. Yeah, it sounds like it's something electrical just by the comment you made about the horn sounding week. Does the lights inside your car seem week as well? How about when you turn on your headlights?

 

o god... so u think its hydrolocked?

 

If it just make a click noise, maybe it is the starter. When ever you have a problem with the starter you can usually hear the relay click but nothing would happen because of a dead starter. Or maybe that was the relay failing. One of the two lol. It seems to me that it is something electrical simply because when you try to start it the lights inside go out. Sounds like you have something shorted and when the car is trying to use it it is grounding everything. I am not sure where the starter and relay are on this car because I haven't done engine work yet, but I would assume low and possibly could have shorted that selnoid or relay out.

 

Yep know of two with stock 350Z's with hydrolock motors.

 

Going off the video it acts like a dead battery because all the lights shut off when you turn the key. Since the car isn't even turning over I would say it's deffinately something electrical. Be sure to check all your fuses and relays before having it towed to the dealer.

 

Sounds like you killed the battery. Try another battery befor you bring it back to Nissan.

 

+1, a bad starter wouldn't cause your horn to sound weak or your lights to dim. You probably just drained your battery from trying to start it too often before it dried out. Try charging it first.

 

I Hydro-locked a 1997 Eclipse. It can happen. Water is not suppose to go in your motor. Water doesn't combust like fuel, so it causes things to bend in the combustion chamber. What the guy said above is true, "If you get luck" and no damage has already been done. It is true though that most stock intakes are good about keeping water out. I had one of those HKS cold air intakes that was hanging low. It got submersed in the water, and that was the end of my motor. State Farms Insurance covered it under "Flood damage"

 

I have also known multiple people that hydrolocked Honda engines. As for this situation. I think it is the battery. No way your lights should turn off like that when you go to start it.

 

Yeah, but how would the battery die that fast? As soon as he hit water? It sounds like something happened and shorted out. It could have screwed something up to the point where something was getting a constant draw from the battery and it could be dead by the next day but I don't see how hitting a puddle will kill the battery. I don't think it is hydrolocked though because the intake hole is a ways up there and unless the bumper hit the water I don't see how it would get there from the wheels splashing water around. And why do the interior lights light up so bright days later? And when he tries to turn it over it goes COMEPLETELY black? You would think if it was a battery that allowed the lights to be THAT bright that it would dim. And then they come back on jsut as bright as they were before without hesitation. And is that an after market alarm? That sounds loud and seems to work. The horn sounded faint the night it happened could have been due to the bad weather, he said it was really bad and heavy rain hitting the car and high winds could muffle the sound. My horn sometimes sounds muffled. It sounds like something is clicking on from the turn of the key and grounding out the system.

What happens when you try to turn on the headlights? And if it goes to accessory position with still having power, try turning on the radio, does it work?

 

WEll he also said he tried jump starting the car and did not work, so probably it isnt the battery. The horn probably sounds weak becuase it got some water in. I couldnt think of a reason why Nissan would not solve your problem whatever it is if your car is stock, is not like you put it inside a lake or something, you just went through a puddle that got up to your anckles...

This remaind me of the last episode of top gear where they put a pickup truck inside an ocean ateached with some stings it totaly sinks for about 8 hrs and when they take it out it starts.

 

I think this is the best advice right now. It sounds electrical and you weren't doing anything out of the ordinary. Take it to the dealership and tell them it stopped running in the rain and have them take a look at it. If worse comes to worse they'll tell you what's wrong and you'll have to file a claim w/ your insurance.

 

How fast were you going when you hit the water. It is a LONG shot but maybe the force of you hitting the water relocated a wire and or bent something JUST enough to touch a ground, such as the frame or the "K" support. Look underneither and see if everything is ok. I say this is a long shot because of the plastic cover plate, but you never know.

 

I'm still guessing battery.

My theory? the water caused the battery to short out. It basically fried itself. Jumping won't work in this case. I had this exact thing on my Volvo (although it wasn't due to water ... just age) and the ONLY thing that fixed it was a whole new battery.

And, yes, it is still giving off a little juice, hence the weak lights, etc.

 

here is a long shot... one time in my pontiac I hit a pothole and one of the terminals of the battery was loose (I had just put a sound system in), then the car shut off. It was weird cause the lights would turn on but when I tried to start it, it would click and everything shut off like your car. I was like f***. I think the engine rocking when starting shook it. Anyway Im sittin in the pourin rain and I call my dad, he shows up we tried to jump it and it didnt do anything, but then he noticed the terminal tightened it and it started right up. Check all your visible electrical connections to make sure they are all tight and it wasnt the impact.

 

It has to be something electrical (ie battery, starter), no way that 3-5 inches of water hydrolocked an engine with stock air intake. Just my $ 0.02

 

Thanks for all the replies guys, and to answer a few questions. Was going 30mph, have tried to jump start the car many times, the lights are so bright because it was at nite when i took that, not day. My car is lower now with the bodykit, so yes the bumper did hit the water, and lets say what if i had a CAI would that hydrolock my car? does it sound hydrolocked?

iam about to go over there and try it again, ill keep you updated.

 

Not sure that would happen, the battery is fused at the + terminal. I'll run this problem by our Master Tech and see what he thinks.

Just spoke to him, your problem is the MAF sensor in his opinion. You will need a new one.
