Re: Car won't start!! After I washed it or when it gets...
A couple things to try... first get some gas line antifreeze... yes alcohol (not the kind you drink) and put it in the tank on the outside chance water is in the tank.
second to eliminate the idea that water is shorting out the ignition spray wd 40 on all the wires and the coil distributer cap etc. any ignition parts that you can reach. wd 40 is oil... it does not conduct electricity.
second thing.... try to start the car when it is dark.... even if it won't start if there is any arcing of electricity that will make it easy to see.
P.S it appears water is most likely getting into your fuel OR you have an ignition part that is exposed to water. check all the connectors as well.

I'd say it's the spark plug or distributor cap. Instead of writing out a long explanation, here's one already done for you! Should help...
The most common reason for a car
not starting in the rain is found in the spark plugs. Wire insulation
can wear thin and this causes the voltage to arc to the metal of the car
engine rather then going into the spark plug. You can check for this
visually by opening the hood when it's wet outside and trying to start
the car. You might be able to see an arc from the spark plug wires.
The second most common issue is the distributor cap. Take a good
physical examination of your distributor cap for any signs of a cracks.
Also remove the distributor cap and check the inside of it for moisture.
If you find any, wipe it clean; it won't work while wet.
If a check of the spark plugs and the distribution cap has not
solved your problem, then you have a bigger issue. There are dozens of
other reasons a car won't start, from battery corrosion to a fuel filter
issue keeping gas from reaching the engine. Though few of these other
issues will only affect your vehicle during the rain.
check on the passanger side of the car to see if the floor is getting wet as well because it sounds as if your computer is getting wet behind the glove box while at home on a nice day wash the car and check it all over for leaks because the computer or something is getting wet in the car it may be a bad seal around the windshield
No, I think he has the same problem I do. I have a stock 99 malibu...no real theft system. Usually after it rains or gets cold, a "theft system" light comes on in my dash. I can be driving, and the light will come on. If I turn the car off, I cannot restart the vehicle till about 20 minutes have passed and the light finally goes off. Sometimes this light comes on when I try to start the car in the morning. I put the key in the ignition, and the car will not start for 20 minutes till the darn theft system light goes off. From what I gathered, the theft system issue has something to do with a "passlock II" defect. I have no idea what this is, all I know is that I can't get a mechanic to listen to me, because the issue never repeats itself when I go to a garage. It gets a little annoying, but I've learned to deal with it.
What you can do to diagnose this issue is - take an old spray bottle
(some kind of house cleaning solution), clean it out really well (so
nothing flammable is in it) and fill it with water. Then, pop the hood
to your car, start the engine, and squirt different parts of your
engine until you squirt an engine part that causes your car to shut
off... then you know that's the problem part!
I had the same issue with my
husband's car. We determined that it was the distributor cap, which we
purchased at Auto Zone and replaced on our own for like $30.
