Answer
Hi Bert,
The only 'simple' possibility is that the exhaust gas recirculation valve is sticking ajar, which leans the mixture too much for combustion to occur when starting and so gives the appearance of flooding. You can find it under the throttle body at the end of engine on the right side of the car. If you can see a valve pintel (or stem) between the vacuum operator on the top of the assembly and the valve body that actually attaches to the pipe that carries the exhaust gas, try spraying some WD-40 on the place where the pintel inters the body to lubricate its motion. If there is a slot in the pintel where you can insert the tip of a screwdriver do so and lever the stem back and forth to free up its motion. Crud can inter that area and when the engine is turned off, instead of the valve closing, it stick ajar. This just happened to me a couple of days ago in our '89 Lebaron.
Other than that, a fault code readout would be the best way to get a clue as to what else might be wrong. Try using the ignition key:"On-off-on-off-on and leave on" doing that is an elapsed time of 5 seconds or less. Then watch the odometer window to see if the mileage reading is replaced by any 4-digit numbers, which are fault codes. If not, then a readout with an OBD-II reader via a plug under the dash to the right of the steering column is the only way to get the numbers. Write back if you can get any code numbers and we'll go from there.
