Update: Heavy Rain, Won't Start?

[Donne Trav]

Like I stated in the previous thread ("Heavy Rain, Won"t Start"), after
sitting a few days. the car starts right up. Well, it did just that. I barely turned the key, and wham, started right up! The sun's out brightly, 50ish temperature, nice evening — something that was moist/damp isn't anymore. Go figure. I guess when my tired bone feel up to it, I'll change my coil wire and investigate the electrical wire that attaches to the Opti. I was told the terminals could have a slight of corrosion which might hold moisture. I don't know.:confused

my buddy has a truck that was acting the exact same way. he pulled the computer and sealed all the seams with silicone, and used a bit of silicone where the connector hits the computer. not one problem since.

It runs ok if you drive through large water puddles ?? Does it start after you drive through lots of water ?
If so the water has to be getting into something from the top.
On a nice warm sunny day you might want to get the hose out and run water on select spots on the cowl, starting towards the outside and trying it each time you move. Might show where to look.

Scav.

The symptoms that I have experienced with that connector on the opti when it gets wet or corroded are as follows

1. Car will crank but not fire
2. Occasionally after I have cranked it a few times it may try to run.
3. When it trys to run it gets very rich and then floods out and the ecm shuts down the fuel.

If I take the electrical plug out and blow compressed air at the connector and then try to start it it fires right up clears out the flooded cylinders and no more problems. I now use a heavy dose of dielectric grease on that connector.

Sounds Good! That'll be the first thing I do -- weather permitting.
I'll even go the "extra mile" and swap out the coil wire, since I forgot to
when I, myself, me, all alone, changed those freegin' plug wires 2 1/2 yrs ago.
That was the first & most exasperating chore I've done on my ride to date.
Thanks a heap for the info.
