If it is actually getting too much fuel, the injector or injectors are staying on too long. They are controlled by the ECM so nothing to do with the ignition system.
Another possible cause is a bad fuel pressure regulator. But none of this should be connected to the a/c.
Very strange.

underneth the intake manold is were your fuel injector poppet nozzles are, more than likely the fuel line hose that goes thru the back of the intake is split and leaking fuel underneth the intake manifold if you check the fuel pressure you will find that the fuel pressure will drop down to 0 psi as soon as the fuel pump shuts off and it should hold pressure

Check for antifreeze leak, make white smoke under hood, and check your antifreeze level

before you drop tank again, check fuses & relay.then disconnect fuel line @ filter turn key to on position should hear fuel pump run and get gas stream out of line. if no flow from line new pump faulty be sure & remove negative battery cable first good luck.
