I changed my injectors today, and when I turn the key ON, the pump wont pressurize (no humming) but the relays click as normal. There is also no pressure at the rail obviously.

Pump is 2 years old and worked great before the injectors.

SUGGESTIONS?

Blown fuse? Can you take the line off going into your filter and see if you get fuel flow there?

I pounded on the tank, and it came to life...the truck was sitting for a week, if it matters...

Thx all.

Check the ground going to the sending unit and pump. In fact clean it. Then you know you can rule that out.
