check you have power from the battery.

There are four things required for an engine to run: air, fuel, compression and properly timed spark. If you have fuel and timed spark, the only two variables are air and compression. Air is not the likely problem, and compression should be good unless you blew a head gasket or the rings in all four cylinders. How did you determine that you have fuel and spark? Those are the two most likely problem areas.

may be you should make a diagnostic and you can do it in a garage or you can do it by yourself if you want to do it by yourself you need some tools and you can find some good ones here: http://www.xcardiag.com

sounds like a security issue or possibly a bad bcm, may be hard to diagnose due to it being intermittant, have you pulled codes

sound like the starter is bad .replace it.

Do you have any vehicle knowledge or experience?
Are you working in your driveway?
If so,why did you change the module? No parts get changed without an understanding of what they do, and some testing. Only change things when they fail a test.

There is no specific,"What Is Next". Every technician, has their own sequence they follow, when diagnosing an issue.

all gm vehicles from 97-2005 have a theft system called the passlock system. (how to deactivate system on chevy malibu) turn key on engine off, let it stay on for at least 10 minutes, then turn ignition off, take out key from ignition switch. after 1 minute start the car. you can also go to tubesound.com to disable system for good. --tubesound.com/passlocksystem. ( just type in the problem when page comes up ). have a good day!! vehicle will not start with system blinking. it thinks its being stolen.

have you checked or replaced the starter relay?

I own a 1998 Chevy Malibu personally, change the ignition switch I had the identical issue, the switch eventually stopped turning completely, my vehicle had to be towed!! Save yourself a headache, I got one from a junkyard for 2.00, but it had to be programmed for the vehicle, I would take it to a trusted shop or dealer.
