ya but its been veiwed a million times. its nearly viral. LOL
take the sending unit out of the tank. keep ALL the lines connected. cap the line at the pick-up to lift pump connection and put a few PSI of compressed air to it. this is where you will get air into the system that will F$$$ with you. (the suction side of the system.) you will see no visable signs of a leak while operating the truck. all other sections of fuel line will pysically leak fuel because they are under some kind of pressure. if you have no leak after the test. take your injection pump off because something is going on.
fuel and air is all a diesel needs. if your getting air to the cylinders and unmolested fuel to the pump than its the fuel delivery piece by default.

Well after a long battle, found out what happened.
First I figured I would change the fuel filter one more time to be sure, still the same issue.
Dropped the tank, checked the draw straw and gaskets/ return lines etc around the tank. Still having an issue.
Checked all the lines to make sure they were all tight, which they all were. Checked all the fittings in and out. Still having an issue.
Double checked ofv and all my DV and injectors, all tight.
I had already installed a check valve on the return line.
After a bunch of f bombs and mental breakdowns I figured screw it.
Found an old Holley pump laying in my garage and figured hey why not try to plumb this up. Got all the fittings and things I would need.
Hooked it up today,wired it into a key on circuit.
bam, fires right up without hesitation.
Im guessing that the mechanical lift pump didn't have the sack to fire over with the big lines connected, but either way now its like a dream.
Yes both pumps are hooked up.
I would like to thank all of you for your help through this.

I had issues with my stock lift pump doing the same thing and it was all stock then one day at -30 wouldn't start so I put a elec pup in to get it into shop after that I disconnected the lift pump and run a elec lift pump this was the 3rd and final lift pump
things I like about the elec lit pump when i change filters I open the bleeder and turn key on no more pumping by hand
and it starts so much better
glad you have it fixed
