I changed my fuel pump and fuel filter on my 1997 tahoe it ran for about 3 hours and now it will not start.My check engine light came on after i changed the fuel pump it wasnt on before i changed it. It will not pull any codes and i cant test the fuel regulator.I can hear the fuel pump and its very strong. I checked some of my spark plugs to see if it was fireing and it is so im just totally lost........
