Cranks but no start?

I just changed my cam and crank sensor, and I had no problem for about 3 months. One morning I tried to start to go to work and the engine cranked, but no start. I took my battery to be checked it's good and got recharged but still won't start. It's not giving me any codes or check engine light isn't on. Nor did it give me any signs it was about to not start. Any ideas about this issue?

Hi,

In most cases, this is either caused by a lack of fuel or no ignition spark. I need you to try something.

See if it starts for a couple of seconds using starting fluid. If it does, then we know it is a fuel-related issue. If there is no change, check for an ignition spark to the plugs.

Here is a link that explains how it's done:

Let me know what you find.
