After washing motor car wont start. i have used air hose and dried every thing and changed the coil but it wont start

Check the distributor for water. Check all of the electrical connections to make sure they are dry. Check a spark plug to see if you are getting a spark by pulling off a plug wire, holding it close to a ground source and cranking over the engine.

Change distributor, rotor, plugs and wires. Make sure you have pushed coil wire on tight on both ends. Also when did you last change the air filter? Motor needs enough air to mix with gas in cylinders to fire.

Dealer washed it, he should fix it. They don't like that 'cos they have to pay the mechanic.. BUT.. Basically there is water somewhere it shouldn't be. First thing I would do is remove the distributer cap, check inside for any sign of dampness or droplets. Wipe it out thoroughly with tissue or soft cloth. Secondly I would find a source of high pressure air, (perhaps dealer will help here) and blow out all visible wire connections and connection blocks, especially around the ignition coil, then spray all of them lightly with WD40. Allow WD40 to dry before restarting. Open up the air filter box and make sure it's not full of water. This is very basic stuff, and it's all can tell you right now, as I'm not a mechanic. Hope it helps.

If you can, air dry the complete engine compartment where you used water to clean it. Possibly a few electrical connectors to the ignition system are wet. If you can disconnect these and air dry them, it may help. If you have not performed any type of maintenance like tune up, good time to do so.

Everyone is missing the main thing here, you just WASHED the motor. You got water in the ignition system. It would be helpful if I knew which motor you had, 2.3, 2.5, or 3.0. If you have the 2.5 or 3.0, you should remove the distributor cap and spray some WD-40 in it, let it dry, and reinstall. WD-40 was a military invention, and the name stands for Water Drier-40th formulation. It was designed to displace water and lubricate to prevent rust where the water was. If you have the 2.3, you will have to remove the 4 bolts that hold the cover on the top of the motor, unplug the electrical connector at the end of that cover, and lift it straight up off of the motor. Underneath the cover you will find what they call the coil cover. This actually acts as your spark plug wires, distributing the energy from your ignition coils (there are 2 under the coil cover) to the spark plugs. There are 4 "boots" that probably stayed on your spark plugs when you pulled the cover off, you will need to remove them from your spark plugs and put them back on the coil cover when you are ready to reinstall it. You will find 6 VERY SMALL BOLTS holding the coil cover on the main cover, remove them and the coil cover will easily come off. Dry the inside of this as stated above with the other 2 engines, allow to dry, wipe it out and return it as you removed it.

Let it dry out. but check by the cap and rotor. or the coil pack. Water and power dont mix...

just sounds like something has got wet that sholdnt have, when it dries the vehicle will start again. i had one and i was washing the engine off at the car wash, done the same thing, died, and wouldnt start. got the coil dried back off, wires, and distributor and cap, and it fired right back up..

if car turn over not start could be many things.faulty fuel pump.broken or stripped time belt.bad spark plugs.broken loose or disconnected wires at the ignition coils or a bad mass air flow sensor.its best to hook car to scanner.to help pinpoint problem faster.

give every thing a good spray with WD40 that may help start her up,, its a bad idear to use a high presher water hose for cleaning your engine up,,
you just found out way that is! she will go again after she has dryed off again,,

You have wet ignition components. Get an air hose and blow dry everything you can get to. You may even have to let it sit to dry out.
