Agree its most likely the fuel pump. Had a chevy van do the same thing some years ago. Befor the engine is running, the computer assumes the pressure at the fuel rail is where its supposed to be and controls how much fuel it injects by opening the injectors for a set period of time. If pressure is low, there isn't enough fuel delivered through the injectors to start the engine. Once the engin starts, the computer adjusts the length of time the injectors are open based on RPM and throttle position, and can compensate somewhat for a weak pump. There's a schrader valve on the fuel rail that you can connect a guage to. The manual should tell you what pressure there should be with the engine not running. The fact that it tries to start would indicate that there's some fuel, so its probably not an electrical problem. Some Chevy's also have a pressure damper on top of the pump that can also fail, but if I had to go to the trouble to drop the tank I'd replace everything in there. Keith
