Could be a vac leak or a problem with the EGR valve among other things. Fuel pressure regulator comes to mind too.
If you did not use a GM pump I would recheck your fuel pressure.
If you have the vortec engine it takes at least 65psi of fuel pressure to make it run.

See if cleaning the throttle body helps -

TUTORIAL HOW TO clean Vortec Throttle body 5 7L Chevy Gmc

I have replaced many injector driver modules on these diesels. GM has redesigned it and i have never had a replacement one fail. This is a known problem for the 6.5 diesel. Unfortunately its about a 500 dollar part from the dealer, and requires intake removal, and some very tight work space to replace.

Sounds alot like the ignition sensor. In my old Chevys it was under the dist cap, mounted on the dist itself. Mine was flat, slightly curved rectangle shape, with two flat prongs coming out both sides. If it would get an internal break in it, you cant see it. I would have the same problem as you, part was only about $12. And comes out with unscrewing two screws.
Might want to give it a shot.

The fuel pump specs are 14 psi. and 20 gallons an hour.

I'd be replacing oil sender. GM have used oil pressure switch as a safety shut-off to fuel pump, when oil pressure drops off, as it would in a collision, due to engine stall.

it is most likely **** in your gas tank  the **** gets stuck in the fuel pump and then it wont send fuel let me know what you  think
