1997 LHS won't start
I have a 97 LHS that has been a great car and never given me problems until a few days ago. I parked it outside the garage and it got to 2 degrees overnight. It wouldn't start in the morning. I have a half tank of gas. I am due for an oil change and have 10W30 in it right now. During winter months, I typically change over to 5W30.
When I turn the key, I can hear the starter turning over the engine quickly, but it won't fire. I tried using starting fluid and it didn't work. I've been putting my battery inside when I'm not using it and using an emergency starter thing when I try to start it.
Should I try to change the oil and see if it will start, should I somehow heat the engine? Your input will be greatly appreciated.
