Are you using the original key that came with the car? The chip in that key may have gone bad. Try using the spare key that should have come with the purchase of the car. You may also be having battery issues. If all else fails....call the people who really know how to rape you...DUM Dum dummmmm....the dealer

SOURCE: how to replace valve cover gasket 1998 chevy malibu

The first step is to remove all the parts that are in the way of you being able to remove the valve covers. (Ex.: air intake, loose wires etc.) Then you will need to remove your valve covers (using basic tools) and be very careful to not let anything get on your lifters, which your valve covers protect. Once you have the valve covers off compare the new gaskets to make sure they are the right size. Then remove the old gasket and replace with the new one using a high temp gasket sealant (available at any auto parts store) to attach the gasket to the valve covers. Then tighten down snug and check for leaks after replaced.

there are two components that you should be looking at one is called a throttle position sensor and the other is a idle air control motor/valve.these two will make the car hard star or not start at all.the are both located in the general area of the intake manifold right where the throttle cable connects.
