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

Robert:

I'm guessing that you're getting some condensation into the electrical connectors on the fuel injectors themselves. The fact that the problem goes away after you drive a bit is the tip off (the moisture evaporates as the engine heats up). I've had similar problems on LH-cars after using engine degreaser and rinsing the engine compartment with a hose. Open up the connectors (they're held together with little rectangular wire springs; you can compress them with a small screwdriver blade to get them open) and dab a bit of dielectric tune up grease (any auto parts store should have this, comes in a small tube) on each contact.

Also good advice by another poser to attend to the FI system grounds. They should be connected to the hold down bolts from the fuel rail to the intake manifold. Remove the bolts, shine up the ring connectors with some emery cloth or sandpaper, apply the dielectric grease and reassemble.

Good luck.
