Okay installed my new gov spring today and now the truck won't run I tryed priming the pump before starting nothing.tryed holding the peddle to the floor nothing I'm sure I have it indexed right any help or tips ? I left my full power screw the same could this be the problem?

 

No, prolly not, crack a line at one or two of the injectors and turn it over, Once you get fuel there to at least one, two would be better, then retighten the injector lines, it may fire right up then, if that's not the problem, you may have installed improperly, I have not installed one yet but you can try my suggestions easily enough with no real losses. Hope it works. Have a better day man, I hope!

 

Did you take the power screw out before doin the spring, and put it back in after replacing the head back on the pump?

utube video (bd gov spring)

 

I pull the full throttle screw before reassembly. I got it running if you want to call it that. A ton of white smoke hardly running stumpling and had to kinda feather the throttle to keep it running

 

Mine did that with the index off.

 

Yeah your indexing is off. The throttle arm has to be rotated clockwise more.

 

What about leaking from the throttle shaft? Normal?

 

No not normal, there is a o ring on that shaft either gone or bad. As for the pin not comming out take the pump top back off and make sure the lever is toward the firewall.
