Other Fuel System Tank Assembly problems of the 2000 Chevrolet Malibu

I've replaced battery, head gaskets, overflow tank, air system connectors, water pump, pcv valve, evap canister, spark plugs, spark plug wires, radiator, camshaft sensor, coolant temp sensor, but my car is still leaking coolant from underneath lower intake manifold and isn't trying to start. I've spent over $2000 and still haven't seen results or got it to fully function. Last time I drove it was on regular georgia roads going to and coming home from work when it over heated twice going both ways.

On sept. 29, 2010, I bought a 2000 chevy Malibu in NY from a NJ dealer, the next day I noticed the check engine light on, so I took the car to a mechanic who told me that there was an issue with the gas emissions. I paid him to do a special emissions gas treatment, the check engine light remained on. The same car also has exterior lighting issues (the turn signals sporadically work and suddenly stop without warning and the emergency blinkers won't work either), I am submitting this because it is possibly related to the recall gas tank issues of this make, model and year car. Today when I contacted Chevrolet recall 800-630-2438 they informed me that the recalls are VIN specific and that my car's VIN # is not on that list and that they can not fix my car. ???.
