yea you have no fuel and sound like a bad harness and the gm's are know for there fuel pump harness's! did you change it when you changed the pump? there is a lose connection somewhere in the fuel delivery system and it's pretty simply! i would check the fuel pump relay on the left hand side of the engine compartment and maybe even put power to the pump at the relay position "b" on the fuel pump relay harness and there should be a one pin connector to put power to also connected to the same position on the relay "b" the wire should be tan and white! good luck
If the punp is bad it won't run at all. Check the throttle body injectors to see if fuel is coming out of both injectors. Sounds like one of the injectors is not working. If one is not working you can check to see if it is the injector or wiring by switching injector wires and see if the problem changed from one injector to the other.
The "spider" up under the plastic intake plenm, the poppets athe end of each of the plastic tubes that supply the fuel to the cylinders get carbon on them and cant spray fuel. to buy a new one at GM its $550.00 Gm is the oly place you should look for one no matter the price aftermarket "copies" are not the same and while you are in there change the fuel prssure regulator at the sam time they are bot a big problem with the vortec
Change the fuel filte also and then EVERY EVERY 15,000 mles and don't worry about the engine oil change that once every 4 or 5 years that is not nearly as important as the fuel filter nothing will happen just remember the fuel filter and forget oil changes don't worry about all that 3000 mile stuff.
