Starting problems.

When I start my jeep sometimes it takes a while for it to start. It turns for about 5 or 6 seconds. I don't think it's my starter because it seems to turn over fine. What is it?

Possibly an ignition timing issue?

Try turning the key to ignition and count 5 before cranking. This will give your fuel pump a few seconds to pressurize the fuel rail. At minimum it will check the fuel delivery.

Could it be my spark plugs?

Try what jimsjeep said. If it starts right away then it could be a problem in your fuel pump. Fuel pump is designed to hold pressure in your fuel rail while the engine is turned off. That way there is fuel present up top when you hit the key to start the engine. Some people refer to this as the check valve in the fuel pump. Try it and see what happens. Turn the key to the run position, you will here the fuel pump run, wait 5 seconds then try to start. There are many threads on here about this. Try searching hard start or something similar.

I would check the most obvious and cheapest first. Thoroughly clean and tightened your battery terminals. If your battery is a few years old, it may need replacing. Drive it to autozone to have the battery/alternator load tested. If all is well, then have the fuel pressure checked.
