I have a 91 LS400 and it won't start. I was out of town for 4 days and came back to find this problem. I jumped it off and it started. My wife drove it to work about 10 minutes away. When she came out to start it at the end of the day it would not start again. I thought it might be a battery even though it is less than 3 years old. I had the battery tested and they said most likely it is bad. I replaced battery and it still won't start. It doesn't sound like the starter is being engaged...it doesn't do anything when you try to start it. Can anyone help?
