'86 Carrera won't start
Hello everyone,
This evening I took my '86 Carrera through a "touchless" car wash. I pulled in, killed the engine, and let the high pressure jets wipe the dirt and road dust off my car. After the wash I started the car and drove it through the dryer and into the parking lot where I stopped the car again to finish drying it with a towel. After another 5 to 10 minutes I attempted to start the car with little effect. It sounded like the starter was turning the engine, but that there was no combustion taking place. Applying more gas eventually caused the engine to make a muffled "putt" once or twice before stopping. I let the car sit for about half an hour thinking that I had perhaps flooded the engine with gas, but there was no change in behaviour. If water was forced into the engine, (through the exhaust perhaps?) will it be able to drain on its own? All the electonics seem to work. Since the starter seems to work, does this rule out a bad DME Relay? Perhaps it shorted? Any suggestions will be appreciated. Thanks, Grant |

Grant,
You might ask a moderator to move this to the "911 tech forum" as this is the off topic forum. You would get a lot more advise and help in the other forum. Personally my 911 never goes in a wash like this. There are far too many electrical connections on the engine and now there is a good chance that you have gotten water in many if not all of them. Water was not forced into the exhaust, but if it was it could possibly destroy the engine. Your cranking it over shows that there is no water inside the cylinders. Water did not get inside the passenger area and the car ran before the wash job, so I would doubt the DME relay, which is under the drivers side seat. Try cleaning the electrical connections on the engine. Get some spray contact cleaner and spray in both ends (the cable and where it connects to the sensor on the engine) and let it dry then replace the cable. Do this with every connection you can find and you might also do this with the distributor cap and coil wires. Then try to start it again... and stay away from car washes in your 911! Joe A

It will prolly dry out and start. Water down through the engine vent I would suspect.
Joe is correct. Best stay out of car washes.
