If you mean the engine will not even turn over when you key then check for the amber security light on the instrument panel. The car will not attempt to crank when that light is on. I have that problem with my lesabre from time to time. I have to wiggle the large wiring harness jacks below the steering column several times and it usually works.

Why won't my engine start on first try?

Could be the fuel pump relay, or the check valve in the pump.
You may not have full fuel pressure after the engine is off for a time.
A mechanic could check the fuel pressure with a gauge before and after cranking the engine.

My 2003 chevy malibu cranks but wont start. battery is good and altenator is good

To clarify - - if the engine cranks the battery and starter are ok.
The alternator does not come into play until the engine is running.
If it cranks but won't start, you have to figure out if you are missing fuel to the injectors or spark to the plugs to proceed.
A mechanic would check that and if there are any trouble codes stored in the computer.

Car cranked for about 5 seconds then everything went dead. Battery is good, fuses on left side of the steering collum good. 1997 buick lesabre 3.8 L engine. Is there a fusable link somewhere? Could not...

I would check the connections at the battery for the pos. and neg. posts or side posts. If it cranked, then it should keep on cranking for more than 5 sec if the connections are good and the battery is fully charged.

There are fusible links, but they generally won't blow because of cranking.

Good luck on this repair.
