GSL-SE wet starting issues
well... everytime there is a heavy rain, and my car sits in it for hours, it wont start. i have to let it dry out for many hours before it will start again. during that time, i checked the spark and it was good. i sprayed gas in intake to make sure it was getting gas and it still wouldnt kick. so... after it sits and like.. dries out, it will fire up, but shoot a TON of smoke and run really rought for a min or two, then i will clear out and run fine until next time. i have no clue what could be getting wet and screwin everthing up. its getting spark and gas. PLEASE HELP!

Water in an electrical connector can do this. Can you test the check engine codes? find the sensor that is causing trouble and fill the connector with dielectric grease to keep water out. MAF maybe?

I had the EXACT SAME PROBLEM with my 84 gsl. If it was just showers, no problem. But an all day heavy rain, NO GO. The irony is that I found every time this happened it was because the engine was flooded. I dont know if you have a carb or injection, but here is what cured my problem: The negative battery cable was not grounded well enough to the strut tower.,the engine was not turning over fast enough, and it would flood. Why every time it rained, is still a mystery. But sand the crap out of the the end of the cable that attaches to the tower, and sand the connection point down to bare metal, then coat with white grease to repel water. Give it a try and see what happens.

Now I'm wondering if you have a poor connection on a temp sensor. That would tell the computer that the engine is cold, causing it to run rich which could lead to flooding in a warm engine...

Remove all vital connections. Inspect for miosture or corrosion. Scrape the terminals clean, fill with dielectric grease and reassemble. Temps sensor makes sense. MAF too. But I said that already.
