My engine bay was sort of dusty and crudy looking so I washed it and now it looks great. The car started no trouble. But then it started to act as if it were going to stall out. I gave it a few shots of gas and left it about 20 minutes at idle to dry off and shut the engine off. 1/2 hour later I left to go for a drive and the car ran like the sweet thing she is until the engine just shut off. I pulled over and for several minutes tried to restart, no luck. Towed it home and left it sit over night, still wont start. I notices that when cranking there was no oil pressure buildup so I popped the hood and pulled and replugged everything that looked like a sensor on the engine and tried again. this time I got the oil pressure to show it was building during crank but still wont start. I pulled the first plug wire off and stuck a screw driver in the end and placed that near the exhust manifold and there does not seem to be any spark.
This is a 1987 300E Straight six of course, new wire in April of 07 new cap and rotor in 06 new plugs. I would say the only thing I have not changed is the coil...Is there a test for this.
Sorry this is so long winded....car has just under 200000 miles.

There is water in the dist cap.

I did this on my C280 once and i found that water got into the spark plug ports....Took the plugs out, sucked the water, used a hari dryer for a few minutes and all was perfect....

Have you checked your plugs for water?

Water in the crankshaft position sensor's terminal ? That could take longer to dry unless you pull it out and dry it.

I used to engage in the engine washing practice, but no more! Too many moisture-sensitive electrical components with newer (post 1990) cars!

I have had issues 100% of the times I did so with the W124...including A/C failure!! The issues sorted themselves out after a few days, but it is really annoying!

If you MUST do so, expect to just pull it in the garage and not drive it for a week. Things will dry out enough by then...

never wash a engine! it has built up its grease coatings, and if you remove them not only will the positioning of elements go into disaray, but why would you open up a TV and wash it cause it was possibly dirty? You would think it wouldn't work either!

I like to keep mine clean so I can see if anything starts leaking. I haven't had any problems so far. I do go to pains to avoid spraying water into areas where there are electrical components anymore than I have to.

God this is a common thing... I did the sme thing to my 380SE euro and tried to start it. No start. Waited a little bit and it started but stumbled like crazy and ran on an odd number of cylinders. Come to find out that when I got it running the water cracked the coil wire tower on the Dist cap. Do be weary on a thorough engine wash...

Back in the old days, we always sprayed WD40 in the distributor cap and it worked.

I am terrified of water damage on something that would take a long time to diagnois...not to mention the pain of getting what ever was needed to replace it...especially on my 500 SEC...

Whenever I power wash my engine, I use a plastic bag to cover the distributor cap and any other sensitive electronic components.....
