I am trying to start an V10 Triton. The engine turns over, but never catches. The truck hasn't been run in a couple of years. What is it likely to be?

Is there an electric fuel pump that should be running when I turn the key? (there is no sound of a fuel pump).

It is either fuel or spark. Fuel injectors?

I'd appreciate any suggestions or comments. Thanks.

 

Test for power to fuel pump and fuel pressure at the rails.
