No Start

2001 7.3
4" turbo back
6637
Edge evo on level 1
38r
BD trans
Reg return
New CPS, IPR, ICP about a year ago

Drove to work this morning and the trans was shifting all over the place so i decided to return the tune to stock and take it for a burn. Trans still shifts bad but when i got to work i noticed a bit of a knock at idle and shut it off. Started fine 9 hours later, ran for a minute then started to run like a turd and eventually died.

The motor cranks fine
Tach moves while cranking
Tried starting with ICP sensor unplugged
Engine oil in pan and hpop is full
Fuel level is nearly full

I put the regulated return on 5 days ago along with 5/8" pickup, fuel lab pump and pre/post filters. When i was setting initial fuel pressure with pump on engine off, i couldn't get the fuel pressure gauge on the regulator to move. I decided to start the motor anyways and after 5-10 seconds the gauge started to register. I set pressure at 65psi at operating temp. I still couldn't get the gauge to move with pump on engine off but it works fine when running.

I'm going to try a new CPS tomorrow. Could this be a regulator problem? I know it's getting fuel to the regulator since i unthreaded the gauge a bit and fuel came out with the pump on.

Anyone have any ideas?

Tried a CPS in the middle of my shift today and the truck started fine. I ran it for a few minutes then shut it off. Went to leave work and the truck ran for a minute then started to sputter. Fuel pressure was around 50 so i tried to bump it up but it wasnt getting any higher and eventually went low enough to stop the motor.

I still can't get ANY fuel pressure on ANY gauge i put on the regulator with the pump on engine off. I backed the regulator adjuster screw ALL the way out and removed a hose off the regulator and turned the fuel pump on and fuel came pouring out.

Their is smoke out the tailpipe while cranking.

This is a driven diesel reg return kit from strictly.

Does ANYONE have any ideas

Dead fuel pump, or plugged pickup tube.

Dropped the tank today and found the pickup tube at the bottom of the tank. I guess i only put it on hand tight when i was measuring/cutting the tube length. Gave my head a shake, threw it all back together and all is good.
