Just bought a 2000 Tahoe very well maintained, 3rd owner 200,000 hwy miles.

What is your question?

5.3 Vortec anyway took along roadtrip about 4000 miles ran great got home let it idle in driveway and it quit and won't start now. It's been totally babied by previous owners and it's been through dirt, mud and everything else with us I'm thinking fuel filter what do you think. Someone said catallatyc converter.
