No start

[darkhaven]

have a 2000 ls v6 automatic. shes drove like a top for the last 230,000 miles but yesterday i went to start her and she will crank but wont start i hooked up my fuel pressure gage and can verify that im getting fuel. is there any common things i should check?

Is the PATS light flashing during the attempted start?
Is battery voltage good?

the ptas light goes out when i put the key in and stays out while cranking, the battery has 11.6v while cranking 12.5ish while not under load. battery term conections have no voltage drop across them.

how cold is it? mine wont start very well when its really cold out. I put heet in it and that seems to help but this is along the long list of problems with these cars and tomorrow that might change.....
