Why won’t my truck crank?

We have replaced computer, fuel pump and filter and oil sending unit and rebuilt distributor. Cleans battery terminals and checked all wires. Firing at all plugs. Will turn over but not crank. Can spray ether into throttle body and it will crank and run fine. HELP

Answer this question I have this problem too

Is this a good question?

@mhunter24 besides the enigne size, what exact year and model is this? What have you checked?

Will turn over but not crank. So it turns over but does not fire?

The injectors are not pulsating. They will spray for a second or two then stop. Engine will not crank. Fuel pump should be pumping 9-13. It is pumping 9. This is a brand new fuel pump with new filter

@mhunter24 "Engine will not crank." not crank as in not turning over or just not firing? there is a big difference.....
