Re: F.I. problems when it rains 700 1990

Are you sure that it's your fuel injection? That is, have you checked and/or updated your ignition system? Moisture can definitely affect your ignition system, especially if it is weak at any part of it. Some or all of the spark will find an easier path to ground and will not cross the plug gap in the cylinder. Thus resulting in a misfire or worse, a no start condition when it's wet outside.

If it hasn't been attended to, your ignition system might be needing a new ditributor cap and rotor and/or new wires and/or new plugs. Preferably change them all at once if they're getting old. Perhaps none of this is news to you, but maybe it will help you track down your problem.

The rest of the 12V system is less likely to be grounding out with such a low potential, except perhaps inside the computers - water can affect stuff on that level; maybe it's your ICU getting water in it? The ECU is inside, safe and dry, right?

Hope this helps.
