what i do is apply a gasket sealer to both sides of a new intake gasket and put loc-tite on the intake bolts with a little bit more torque than spec. if you re-torque the bolts it may help but the gasket is likely already deformed and to access the bolts you need to remove certain componets such as the powersteering pump and upper-intake manifold. if you are that far into it you may as well go ahead and pull the lower intake and replace the gasket. if you keep dex-cool in your engine then i would recomend replacing it at least every two years as it contains a sealant in the coolant and it tends to gunk up after time. to drain it open the radiator drain at the front of the radiator on the drivers side and remove the plug on the engine right above the oil filter. when you fill it up remember to open the air bleeders, one on top of the heater pipe that sits on top of the water pump and there may be one on the thermostat housing depending on year. fuel pumps are not usually a problem with the malibu's but a good way to check is to get it to not start and jack up the rear of the car, there is a plug by the rear of the gas tank off to the right that goes to the fuel pump. probe the gray wire with a test light as some body turns the ignition on to prime the fuel pump. if it does (and you dont hear the pump run)you need to replace the fuel pump, if it doesnt then you need to take it to the dealer and have the rest of the system checked out. that prizm is reliable because it is made by toyota.
