On a powerstroke, one or two bad GPs will not typically cause a no-start condition. With the older IDI style engines, one will bad GP can kill it dead at 40*F!
When you measured your voltage, and it sounds like you did everything correctly, and it's working, how many volts were there (on the output stud)? You NEED to have the same as battery voltage, or at least within 1/2 volt. So if you get 11.5 at the battery (+), you need at LEAST 11.0 at the GPR output terminal.
Given that you just replaced the GPR, I would think this will be ok, but if it's low, check all you wiring back to the battery. You may just have a bad power connection.
Also, a weak starter may not spin the engine fast enough to get it to start. It turns over, just not fast enough. I have seen that before.
