it was one of those "touchless" car washes. My Disco stalled out in the middle of the wash. At first, it wouldn't start at all. Then it would start up, but die out immediately. After several more attempts, it would start and run with constant pumping of the accelerator. At 2000 rpm, it kept dropping back to near 0. It wouldn't idle smoothly. Finally smoothed out enough that I tried to get it home (it was still rough and wouldn't go above 20 mph). When the grade of the street started to rise, it simple quit altogether. A friend towed it home, and now it is DOA. The starter is strong, but the engine will not fire. I can't see any H2O anywhere. I sprayed all of the electrical connections under the hood with Electrowash. When the starter turns, Service engine light comes on. May be normal, I can't remember anymore... Any ideas? |

Check your air filter and box for some water. It also sounds like your stepper motor. Pull it out (see tech article) and try to clean it. Also, when you get it running, try one of those gas additives that 'cleans' your engine for water and other contaminants. Good luck! I'm sure the others will chime in. It sounds a lot like my problem when I did a water crossing I wasn't supposed to  .

It probably just needs to dry out. Some of the new carwashes have hi pressure water jets, and you can select underbody option. My 95 has never liked water blasting. Usually comes around after it dries out. There is a couple good recent threads on fording/waterproofing below. Dielectric grease is mentioned alot. Usually WD 40 does an OK job, not great though. Could be your plug wires might be crappy, thats resulted in 'rain=nogo' for me also.

Your crank sensor is wet.
A second possibility would be the MAF being wet but this is unlikely.

I second the crank position sensor (CPS) or the connections on the ECU. |

To wit, I would add all the connections to the 'brain' or GEM unit under the bonnet(that 'black box' by the washer reservoir.) Early in my ownership of the beast, mine would exhibit the same symptoms. One time, after splashing through a puddle about a mile from the dealership, it couldn't get out of its own way. Give the multi-pin connectors a shot of WD-40 or some other electrical contact cleaner/dryer and either make and break the connection a few times or carefully clean them with an appropriate brush.
Since WD-ing (and the careful application of some dielectic grease) the problem has not returned. (Touch wood....)

SG, that's what I meant by the connections on ECU. |

You might want to check O2 sensors, sometimes a short will cause the engine to run terrible if the sensors are not working properly. |

I sprayed all the connectors, without luck. As it turned out, the gas cap wasn't on tight. One bottle of STP gas treatment and 10 minutes later it fired right up. No more problems. Thanks for all the suggestions. |
