Turns over hard, acting like it want to start, plugs have gas on them a little, but it still wont start , it's an 88 LeSabre Limited with the 3800
If the plugs themselves are wet the whole sparking process won't work; the plugs must be dry basically.
Here's what you should try: remove all of the spark plugs and let the whole thing sit open to dry/air out over night.
Or, the thing I've heard from crazy people... remove the plugs and flash the plugs and plug-holes over a few times with a propane torch(be sure to get the plug wires out of the way). Be prepared for fire coming from the plug holes, burn off all that gas from the plugs and from inside the holes.
At this point you shouldn't need to let things sit open since everything burned up... re-insert and tighten up your plugs, hook the wires back up & give it a go.
Another issue encountered, and although it didn't prevent the vehicle from starting, it did cause issues, was that we had a cracked plug. Either move the vehicle into a dark building, or wait for it to get dark outside, and open the hood up. While trying to start, see if you can identify dancing arc's or flashes coming from under the hood... to assist in making things more obvious people suggest spraying water from a misting sprayer over the plug wires(those can potentially fail causing electricity to arc from them as well). Any arc that happens outside of the cylinder is robbing your vehicle of spark/firing power.
Also, as a visual check for spark... remove one plug from a hole and hook its wire to it. Touch the threads of the plug to a bare metal part on the engine and have someone else try to start the car... you should be able to see it sparking. And don't worry, the open cylinder doesn't put out enough gas/fumes to cause an explosion in the few seconds it takes to perform the spark inspection.
If you notice that the plug isn't sparking, make sure that you're grounded to the vehicle and try again. If you cannot get spark at all, your problem is electrical and that will require a more technical approach: cap, rotor, coil, igniter, fuses - somewhere in there.
I hope that turns out well for you.
