Hi I have a 1995 Lexus SC 400 and am having trouble starting it due to bad gas. I had the fuel filter changed once already a the shop and it ran that day but they didnt empty the bad gas. i put some fresh gas and fuel treatment into it bu now it wont start again. Can anyone tell me where the fuel filter is located so i can check it out? also any other suggestions would be appreciated. Thank You.
