I went and grabbed some plugs/wires as a good start, and went ahead and got a new fuel filter. I figure that can't hurt after sitting for that period of time.
I'll go from there... updates soon.

8 time out of ten code 44 is due to low fuel pressure or if one of the two injectors not firing. Injector firing can be easily verified. Low fuel pressure can be due to weak fuel pump or burst in a fuel hose (inside the gas tank) Another common culprit is old fuel pressure regulator diaphragm and weak or broken fuel pressure regulator spring.
