Post wet start

I recently left my 86 911 in the pouring rain, and it won't start. It sputters and has been getting better daily as it dries out. I even got it to rev a couple times at four or five thousand rpms for a couple seconds, but it died. Does anyone have a rational reason as to why this has happened as it has performed flawlessly up to this point? I opened the rotor and it was dry. I also dried the spark plug wires with a hair dryer but no luck. thanks

Hi David,

I don't think its individual spark plug wires. From the sound of your description the problem has a common denominator more upstream unless when you say "it sputters" you mean some of the cylinders are not firing and some are firing. Check under the distributor & ignition coil boot (next to fuel filter) for any wetness along with any wetness around any harness connections inside the engine compartment including the fuse box on the left side of the engine. If you have an engine anaylzer you can check on both the primary/secondary side of the ignition coil. Let me know what you see.................Barry

David..........also check the ground connections (Cylinder No.1 case, Left side of engine compartment & Under the car around where the transmission & engine come together. Make sure the connections are clean & firmly connected. These ground connections over time corrode from moisture/the elements and the connection is not a good hard ground!
