I think water may have been sucked into your air intake. If this is the case and water has entered your air intake, water may have entered the fuel injection system and your valves, which means your e ngine is effectively drowned.

This, of course, all depends on the water having truly entered the air intake. One way to find out is to check your air cleaner. If it happened recently, the air filter will probably still be wet. Further inspection woudl be to remove the valve covers and check to see if there is a milky residue. This would be indicative of water having mixed with gas/oil in the valves.

There are other considerations, like that parts of your electrical system were breached. Shorted fuses, etc..

The bottom line, if you are not going to do major repair work yourself, you're going to need to take it to a mechanic regardless of where the problem lies. There is no adequate way to check your motor or electrical system online, and no one on this or any other web site could give you more than an educated guess. The surest way to find out is to take it to a service station. I would like to be able to tell you that the alternator got fried, or that if you just dry your injectors you will be fine, but I cannot - no one can. Not through a web site.

That is not to say that someone wont get lucky and guess, and fix your problem here, but I am saying that it is remote at best, and would just be a lucky guess. There's just too much that can go wrong when you drive through deep water, and you might replace half your car (exaggeration) before you find out what is wrong. That could be a heck of a lot more expensive than going to a service station.

Take care.

Check the coil - located on the firewall - it probably has a small crack in its plastic housing where moisture could enter when driving through the water. I had the same problem but now all is well after I replaced my coil at a cost of about $30.

My 2000 dodge caravan wont start after going through a flood what could it be?


the ignition wires will need to dry out, if they get soaked it will not start unless you have good wires, when they start to get old they are more prone to not working when they get wet.

this is providing the starter cranks the engine and it did not hydro lock from water getting into the engine.

Went thru a flooded road about 8"deep stalled out


You filled the cylinders with water. You will need to remove all the spark plugs and crank the engine with them out, to push out the water. you will also want to replace the air filter as it is probably saturated with water.

Car turns over but does not start. Battery good


If it over heated, could have bad head gasket's, fill radiator with water, crank engine with radiator cap off, if water is push out of radiator while cranking, bad head gaskets', also remove spark plug's, crank engine if any water, bad head gasket, also when spark plug's removed, check for any water on them.If there is any water on plug's, bad head gasket, also could try doing a cylinder compression test, if bad compression, head gasket, no compression, wont start that way.

I ran out of gas so i put some in now it wont start


After the car is that low that your car stalls, it takes a very long time to get the fuel pumped back up to the engine. keep cranking it. Only in 20-30 seconds bursts so the starter doesn't over heat.
Of course if it tries to start and you get to much gas in the engine, now you have a flooding problem.

Wont start


easiest: is the battery good?
not so easy: was it flooded enough that it could have sucked water in the intake and gotten into the cylinders? the engine could be seized if this happened.

''My flooded car starts but wont stay running after replacing engi


Has the gas tank been drained and let to dry out and then refilled with gas and a water dryer and the fuel filter replaced? If not then you are in for trouble still and this is why is will not run. You are getting fuel and spark. Which means that your fuel pump is working and the starter is fine. Ingnition could be your problem but I would do the gas thing first then move on
