Default Truck smokes whites when trying to start

Somehow route the electric pump as straight as you can to the fuel bowl out of the tank or out of a 5 gallon can. Id go for a 5 gallon can. Pickup in the tank might be clogged.

When I do that I still have to go through the mechanical pump in Valley and I'm not sure it's pumping to injectors at high rpms

put a fuel pressure gauge on it. Highly consider just going EFuel.

I've had a fuel gauge on Schrader valve it reads nothing when cranking and haven't been able to start truck in a few days

As stated above hook the electric pump up to the switch valve and have it push fuel into a bucket if it moves fuel your obvious culprit would be the mechanical pump. It's either sucking air due to cracked hose or its done for. For the price of a new pump I would just go EFuel.

OP my truck was running a good while with 0 PSI on the fuel pump but my fuel bowl would still fill up. Guys on here said the injectors would still run the truck, but just be hard on them.

I replaced the fuel pump and got 55psi immediately.. so the guage/schrader valve wasn't a fluke.

Also for all guys talking e-fuel. New Carter pumps on RiffRaffDiesel are $92. I'd much rather have my truck fixed for $92 and then convert to e-fuel. In my case I also had other issues aside from my fuel pump.

My fuel tank selector is caught between tanks so I removed it and ran the lines straight to front tank return and main. What are the wires to keep the gauge working with no selector valve in place. Selector valve has stuff blocking the sours for front tank and wouldn't let fuel pass through it so I'm hoping that this will let it run correctly now. Waiting for battery's to charge and I'll know for sure

So this all started after running out of fuel and filling it up? Crazy question, it's definitely diesel that was put in and not gas?
Fuel tank selector was blocked so I removed it and ran lines straight to tank to the motor waiting for battery's to charge now and will try to start later on

Sounds like you may have found the problem. Report back with how she runs
