'99 GMC Seirra is fuel injected called TBI (throttle body fuel injection) you need to check the fuel filter and pressure from the fuel pump, using a gauge connected to the fuel line between the pump and TBI (looks like a carburetor) read how many PSI. Just a running pump doesn't mean there is enough fuel pressure.
