92 Silverado 5.7 TBI won't start..............

Got a problem,



Got a 92 Silverado that was in a front end collision. Since the collision happened it wont start. I have spark and if I pour some gas down the TBI it starts right up. My problem seems to be the injectors aren't spraying any fuel. If I pull the plugs of the injectors I have power on 1 of the leads of each injector as it lights up a test light. When I crank the motor the test light seems to dim and flicker so I think I'm getting a pulse. Here's something I think is strange though. If I have someone turn on the key while I listen at the gas fill, the fuel pump comes on but it runs quite a while before it stops, about 30 seconds. On my other two trucks with TBI, the pump runs about 5 seconds and shuts off. I have no gas leaking out anywhere and there's no gas smell while the pump is running so I's not leaking out anywhere. I don't know if it's taking this long to pressurize the fuel system or if the pump has a time out if the system doesn't pressurize in case of a leak. Can anyone help me out here ???? I'm stumped....................
