I have a 99' Ford Escort Zx2 Sport. It ran just fine yesterday. NOw, this morning, I won't start. the battery is completely drained. Let me preface this with the fact that, for MONTHS, my factory alarm has not been working. It's just been dead. NOW, like a hellish miracle, it works! Could the factory alarm have drained my battery over night? I swear it was FINE yesterday.
