If your saying it cranks good, but hard to start, have a helper crank it, while you visually check for spark at the spark plugs. If you have spark everywhere, use a gage and check fuel pressure.

To check for spark, you can pull a spark plug wire, use spark tester or known good spark plug in the plug boot, ground tester to metal part of engine, watch for spark engine cranking.

Can you check for applicable trouble codes? At the least, you need an obd2 code reader to check codes. Your local autostore probably sells code readers.

How long since over-all tune-up?
