Volvo 460 does not start when raining

Nov 15, 2007 1 Replies

Hi all The car is a 460, 2.0 liter automatic, first registered in July 1996. Only about 140.000 kms. About a month ago, the wife drove into a large pool of water on the road and the car died. Since then, we've had various difficulties, but only in or after a heavy rain! What I have done: Replaced all the high tension wires, spark plugs, distributor and rotor arm (they were due anyway). Poured stuff in the fuel tank to get rid off condensation, and measured the engine sensors easily accessible. The car is fine when allowed to spend the night in the garage, but that's not always possible. Car wouldn't start in the wet air this morning. Used the Data Link Connector to read error codes, but all I got was 1 1 1, which is No Fault Found. Going out to test the fuel pump, although it's probably a long shot. I'd be grateful for any other ideas, before the wife completely loses faith in my mechanical skills ;-)

Hmmm. Maybe check the coil? When I've had this problem it was aging insulation on the spark plug wires and coil wires, allowing the wires to ground to the engine block right through the insulation.
