Why is my Cadillac Seville

No lights are on my dash

Could be clogged fuel injectors. Try this by fuel injection cleaner( lucas ) is a good one add this to an empty tank then fill . You may have to do this a few times. Also ck you're exhaust see if you have water dripping out. Add dry gas to the tank

OK well I have a full tank of gas and can't drive nowhere. Lol so I can't put the cleaner in the tank

You may need a new egr valve also ck for vacuum leaks
