Whehn you say trouble starting, are you saying it cranks good but won't start, or it won't even crank? How long since a tune-up? Any applicable codes?

It cranks pretty good, but won't start. Haven't gotten a tune up since 25, 00 miles ago. And there are no codes or lights on

If it cranks good but won't start, have a helper crank it while you check for spark at the plugs. To check for spark at the plugs, You pull a spark plug wire loose, use a spark tester or known good spark plug in the boot. Ground/touch the metal part of tester to metal part of engine, watch for spark. If you have spark everywhere, use a fuel pressure gage and check fuel pressure.

Also, you may need to clean throttle body and idle air control.
