Default engine cranks but won't start

About a week ago I changed the battery and air filter in my 2008 titan. It cranked longer than normal but started and has ran fine since. Now it cranks but won't fire.

Is "service engine soon" light on? Even if not on, scan ECM for trouble codes.

check the starter fuse. Even though the engines cranks over, we found the starter fuse was the problem

Check the 10A IGN fuse.
Also I've read it could be the Fuel pump.

ECM computer relay

It could be the fuel pump or sending unit also.

Or a crank or cam position sensor... There are a lot of "could be's." First thing to do is check to see if it's a fuel delivery problem or an ignition problem if there are no stored codes to help diagnose the problem. Spray carb cleaner into the intake and see if it will "fire" on it. If it does, then the problem is a fuel delivery issue. If it doesn't, then either there is an ignition problem or the plugs are badly fouled. So, check for spark to the plugs. Cam position sensor and crank position sensor failures are more common on these vehicles than failed fuel pumps, but, it's best to diagnose the fault of the problem rather than just throw parts at it.
