How do you start your car after it stalls in water?

Answer 1

Water Logged Engine?First, Disconnect battery, and dry the engine and vehicle inside and out as completely as possible. Give attention and time for electrical wiring to dry as well. Wet wiring and harnesses can cause new shorts and burnouts.

Then, see if the engine will spin. You may have to remove the fan to access the crank nut. If it does not turn by hand then there may be engine damage due to water will not compress. This is called hydro-locking your engine. If it does turn then "is the starter locked up" Be sure not to over look diagnosis of electrical related issues due to water.

Lastly if its a stick shift have some one pull you in gear, with fresh oil in the engine of course, and try to get the oil pumping again to achieve some compression.

take all spark plugs out turn engine over a few times then try to start may have to change plugs fuel and oil at least check! I have a 1997 Jeep Grand Cherokee that wouldn't start after it rained. The problem was simply water getting onto my battery terminals. I bought a new battery and covered the terminals in a waterproof grease. This may help with your situation. Also, check to see if your distributor cap is cracked, I'm not 100% sure about this idea but give it a shot. If you drive through a puddle sometimes water can get your distributor cap wet of even into the car

I drove through a puddle in a 89' Toyota Camiry and had the car die in motion from a distributor cap that FILLED with water. after ensuring that the engine still turns over, The easiest diagnosis for this is to check to see if you still have a "spark". If there is no spark, the first place to try is the distributor cap, then work your way from there. I was lucky. some mopping up and water dispersant (WD-40) and it runs like a top again.

Ethamax is the best choice if you want to remove water out of a fuel tank without paying a mechanic to remove the tank and do the job for you $$$......!

This is not a complete answer.

If your car stalls in water more than 300mm, 12inches deep, it is possible that water will enter your differential. This is because the cold water cools the diff housing and the air inside, and thus will draw water in the breather pipe. You do not want water in your diff. In this case, you should not have your car rope towed, as this may damage the diff. Have it towed on a trailer, and have the diff drained and re-filled with proper oil. How deep the water is makes a difference.

If there is any chance of water in the cylinders. You need to remove the spark plugs. Turning it over with plugs out should blow out most of the water in the cylinders. I have seen engines that have sucked water through the air filter and into the cylinders. When starting was attempted several rods got bent. Some cars take air in close to the head lights. Some even below the head lights
