Question about 1999 Chevrolet Malibu
Back up and start over: gas or spark, which is missing? Do you hear the pump turn on, with key on? If yes, check for spark-maybe ignition system not working. If your new pump is not turning on with key on-it should turn on for a couple of seconds to pressurize the fuel system-try a new fuel pump relay. If your old pump went out, and you were doing some excessive cranking to get it to start, the relay just possibly failed. Some mechanics recommend a new relay when you replace the pump for that very reason.
If pump is working and you have spark, check the fuel pressure, not sure of your requirement, but should be about 50 psi, if like most GM with multiport injection. If pressure is low and your gas filter is clear, and the pressure regulator checks out okay during the pressure test-then you will need to determine if your after market pump is compatible with OEM specifications. Sometimes off brand pumps just don't have the performance of OEM. Again, some mechanics stress to go with OEM, just to prevent future problems with replacement parts.
Don't know, Robert, but I hope you find it. Start with the basic-gas and spark. Post back with what you find.

IF the engine tries to turn over but doesn't then the problem will be related to a flat battery. have a load test done to check for bad cell. battery life is unpredictable and will allow proper performance at one point but total failure a short time later.. Cold weather is a big killer of poor performing batteries

probably not fuel filter . probably going to have to remove the upper intake and replace the fuel injector spider(fuel inj assebly) if it is droping fuel pressure it is leaking into the upper manifold

Cheak your fuse under the drivers side under the hood. Look in your manuel for fuel fuse. It looks like a little black box.

It sounds like the choke is the most likely culprit. Take the air cleaner off the throttle body/Carburater. Have someone cover most of the throttle body/Carburater intake, if you don't have help use a piece of heavy cardboard. If it starts up right away it's the choke. Note: if you use cardboard don't rev the engine you may **** the cardboard into the engine.
I'm afraid with all the different types of choke controls I can't tell you how to fix your choke with out actually seeing it.
