It died 5 months ago when it got extremely cold and since then I hadn't had another vehicle to jumpstart it. I can hear it engage when I turn the key, but it doesn't turn over. The engine light and oil lights are on and the red light on the dash is flashing, which a search indicated it was an anti theft thing? While turning, break and abs come on and it once showed p0153 once but hasn't after that. I just replaced the battery, and I am hoping it's just the ECU acting up after a battery replacement and I was wondering how I reset it.
