Chevrolet: 2002 Chevy Tahoe, chevy tahoe, fuel filter

Question
My friend has a chevy tahoe that possibly ran out of gas and will not restart after putting gas in it.  

Answer
Howard;
Hi you might have air in the line or you could have sucked up some sludge into the fuel filter. so it should be checked and when you try to start it just pump it a lot when turning it over , also check to see if the fuse is blown for the fuel pump
