I have a 1999 Yukon Danali. The car would not start today. I seemed like it was not getting fuel. I turned the key on and I can hear the humm of the fuel pump. I changed the fuel filter since its cheap but still didnt start. I loosened the fuel line from the filter and the fuel spurted out so I know its going that far. I checked the wires for a spark. I poured some gas in the intake to see if it would start and nothing. Im stuck as to what the problem is. Can you help out?
