'01 Suburban hard starting

Have an '01 Suburban with the 5.3 and 130k miles.  It runs good but has trouble starting sometimes.  It takes several attempts to get it started on some occasions, and on others no problem.  One time it took about 6 attempts at cranking before it fired.   I have no clue where to start looking.  There are no codes or warning lites, and when it does start, it runs fine.  Any suggestions where to begin would be a great help.

Thanks

Could need a good fuel injector cleaning.
How long since you replaced the fuel filter, air filter and spark plugs?
