if fuel and fire are getting to the combustion chamber, the engine runs- so one of these things is NOT happening, and it sounds like fuel-

look down in the throttle body while someone cranks it- you should be able to see fuel going into it- if it runs when you dump gas in it, that should tell you something- but why did you replace the manifold? I can't tell what is going on, especially after all that work has been done- but my best guess would be the fuel pump or relay- check to see if you have power going there-

And if your business depends on this unreliable truck, it is time to get something better-

I put in a new fuel pump on a 1997 GMC Sienna 1500. I can hear the fuel pump clicking on but it want fire when i try to crank it.
