I just got done washing my car for the first time and it wouldn't start up right afterwards. It had just been running 5 minutes earlier. I assume it was due to water getting in the cowl vents but am not sure. After sitting for about 10 minutes it started right up. Is this a common occurance? If so, how the heck would I ever drive it in the rain if I had to?

 

Had to be because of the water....I had a friend that used to do that to his 4x4 on occasion but that was due to running in standing water and getting water under the distributor.

Haven't gotten around to fixing my cowl yet so I bought one of those plastic covers to put over it for washing or the surprise thunderstorm and it works to keep the water out. I don't leave it on just put it on as needed. Most of the time it stays in the trunk.

 

I think its more likely that water got on something under your hood.

 

If you get water or condensation under your Dizzy Cap it will not start. If you have an old cap replace it, its only a few bucks.

I washed my engine and bay once (covered the carb and dizzy) and she started right up. Drove to get gas, turned her off, then she started right up again. I pulled out across three lanes of traffic and she died in the 1st lane. Luckily I had enough momentum to get across. The guy in the dump truck coming at me at 65 mph thought I was slowing down just for fun. I pulled the cap and dried it and she started right up.

 

I've had cars that won't run even with a little moisture under the distributor cap. Just pop it off and check.

 

Check under the cap for moisture like said before. If it ever happens again, squirt a little WD40 in the cap and she'll fire right up.

 

thanks for the input guys. i'll definately check the distributor cap next time. on a side note, what harm can be caused by water getting into the cowl vents? just leaking down inside the interior?

 

Shouldn't leak into the car unless the cowl is rotten. The cowls should drain out under the fenders.

 

Yeh, water in the cowl will do nothing but increase your rust in that area. It was will have no affect on the car starting.

My car died twice in the car wash. Come to find out, it was getting water in the MSD box and finally killed it totally. I had to push the car out of the car wash and get a tow. When I replaced the MSD box it fired right up. Water got into something electrical or down the carb on your car. Start drying and using WD40 (water displacement formula 40). That is was it was designed for!

 

yep. mois distributor cap. no need to replace. just dry with paper towel or blow the water out with pressurized air. ....or .. you got water into your carb by either doing a motor wash or not having an airfilter
