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.

Replace the coolant sensor on the front of the intake manifold.The coolant sensors on this engine does go bad and wont set a check engine light. The sensor will read about -32 to 0 degrees when they do go bad. The computer thinks it is that cold and sends tons of fuel to the engine. If you try to start the engine with the throttle depressed to the floor it puts the fuel system in clear flood mode and wont fire the injectors. Engine will start then and run very rich. The coolant sensor has two wires on it and sometimes you need to replace the wiring pigtail going to it as the sensor can seep coolant into the connector and corrode the terminals. All the parts are available at pepboys and autozone or napa. Good luck

fuel pump ok...clean inside the throttle body with spray carb cleaner...make sure the engine is cool and do not start it while real wet with carb clnr...BETTER YET,,,,get yourself a can of SEAFOAM@ (9$), and follow directions on can to clean your fuel system...it works great...your car does smoke while your using it but goes away quickly...makes big diff in the way your 305 runs....hope this helps....thanks
