You could remove number 1 plug and move the piston to top dead center.
Then remove the valve cover to verify the valves for that cylinder are both closed.
Before going there, what is the problem you have?

Ok, you may have a stuck injector that may need to be replaced. I would check this first before going any further with the timing.

Ok, Im going to take my husbands place on here for a moment. Long story short, my car had a bent valve. ( He didnt check the timing before putting the heads on) He put remanufactured heads on. Put everything back together. And the car would turn over, but not start. We would get a backfire from the intake. Thats what propmted him to ask about the timing.

There are different size push rods and if they are put in wrong, it will bend a valve. You need a compression test on that cylinder to verify that it has the ability to work.
