Why won't 2001 Focus start?

Focus sat for several months. I had to put 2 tires for inspection, and the Focus won't start. It tried to start once, after I pushed the fuel reset button, but it only ran the battery down. I charged it and she spins over, but it seems like it doesn't fire like normal. A mechanic told me to by-pass the switch on the fuel reset, and that didn't work either. Just made the paperclip hot. This car ran excellent before I drove another car for a long time last winter. (Explorer has 4WD). It still doesn't have 100K miles yet. The Explorer has 246K miles on it!
