Check to see if timing belt is broke as it is a non interference engine and the computer wont turn on the injectors if it doesn't see cam movement.

My 2002 malibu ls wont start it will turn over but wont fire my check engine light is on but that in no other lights on no window no power locks nothen how do i fix it


If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, check fuel pressure and fuel injector pulse. Go from there.
We can also check circuits for power windows.

My 1998 lexus 300rx will not start, the battery is good


You say it doesn't start. Does it turn over good, but won't fire? Does it click and not turn over? If it turns over good but won't actually start, you would need to check fuel pressure output from pump, check spark coming from distributor to plugs and the control module could be bad if there's no spark, as well as the coils. If it doesn't turn over, but clicks when you turn the key, you could have a bad starter.
