WONT START BUT TRIES.

1999 GMC Yukon • V8 4WD Automatic • 99,000 miles

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?

Your saying, you have good spark at all the plugs, engine cranking? If so, use a gage and check for proper fuel pressure. 60--66 psi.
